Abstract: The experimental results from the various reaction and decay studies leading to nuclides in the A=153 mass chain have been reviewed. These data are summarized and presented, together with the adopted level schemes and properties.

Cutoff Date: Data available prior to December 1980 have been evaluated. In addition, mass data from 82WaZZ have been included.

Acknowledgments: The evaluator is grateful to R. L. Bunting, R. G. Helmer, and C. W. Reich for many helpful discussions. The evaluator also thanks R. C. Greenwood for providing his data prior to publication.

GENERAL ORGANIZATION OF MATERIAL

Within each A-chain, information is collected by isotope and arranged in order of increasing Z. For each isotope, AZ, the arrangement of material and conventions for inclusion in tables are described below. Uncertainties are shown whenever available.

1. Adopted levels in *Z - All adopted level properties are shown for each level, together with explanatory comments.

2. Adopted y-radiations in AZ. 3. Radiations from *Z decay - All adopted radiation properties are shown for each

(1- or y-radiation from decay of the ‘Z ground state. Properties of E-, p+- or p= branches are shown if they have special interest.

4. Radiations from *Z isomeric-state decay - Decay of each isomeric state is presented according to the same conventions as for the ground-state decay.

5. Levels and y-rays in *Z from decay+ - Decays are ordered by A, Z of the parent. a) Table of levels deduced from the decay. b) Table of y-rays observed in the decay unless given under its respective

parent according to 3 or 4 above. 6. Levels and y-rays in AZ from nuclear reactions ’ - Reactions are ordered by A, 2

of the target, then by A, Z of the incident nucleus. A heading is given for each reaction.

a) Table of’levels deduced from the reaction. b) Table of y-rays observed in the reaction.

?’ The detailed results are tabulated only when the information is not adequately summarized on the drawings.

Jr: 5/2C5321 Nilsson state. This band originates in the hl1/2 shell-model state, so most of the strength is expected to be found in the 11/Z member of the band. The weak popuiation of the ground state is consistent with this assignment.

Jr: 5/2C4131 Nilsson state.

Jr: 3/2C4111 Nilsson state

Jr: 1/2C4201 Nilsson state

E(leve1): 78Bul8 indicated that the peak at 935 keV is likely due, in part, to the 9/2+ member of the l/ZC4201 band. This assignment is consistent with the I(I+l) rule.

Jr: probably the 3/2C5411 Nilsson state. The observed value of do/dR for this peak is larger than expected for the 3/2C5411 Nilsson st.ate, so 788~18 attributed part of the intensity to the Q/2+ member of the l/ZC4201 band.

Jr: angular distributions suggest L=2, and negative analyzing power indicates J=L-l/2. The Jr assignment is listed as tentative because the L-transfer is not definite.

Jr: 3/X4221 Nilsson state. JR although the angular distribution is consistent with L=2 and the energy

agreement is good, the analyzing power is not consistent with DWBA curves for L=2, so the Jr assignment is tentative.

t Authors estimate AEs4 keV for E<l500 keV and AE somewhat larger for higher excitations. t Listed J values were assigned by 78Bul8 and are based on comparisons of measured angular distributions of

cross sections and analyzing powers with DWBA predictions. 4 Listed valul?s are spectroscopic factors defined by da/dR(exp)=N*C”S=du/dR(DWBA) with normalization

of the 7.53-keV transition was inferred from cc(L) intensities (69S11104). The small value of the energy spacing in the ground-state band results from the expected strong Coriolis coupling between the ground-state band and higher lying positive-parity orbitals, principally 5/2C6421 and 1/2[6601, arising from the il3/2 spherical shell-model state (71B~16).

‘53Sm Levels from ‘52Sm(n,y) 69Sm04,69Re04,71Be41

The level scheme shown in the drawings is based on data from 69Sm04, 69Re04 and 71Be41. The energy of the capture state was determined from an unweighted average of the values reported by these authors for the energy of the primary transition to the 127.30-keV level. The energies used for the primary transitions from the capture state represent the difference between this value and that of the final state.

for the ‘%d decay. 77Wa08 adopted the value Q(&)=243 keV derived from measurements of the K-capture probability to the 172.85-keV level in lJ3Eu whereas 73Kr24 and 70Ma05 adopted the , “‘Gd(d,p) and ‘e4Gd(d,t) reaction Q values and adjusted the rs3Gd Q(E) value accordingly. The value for S(n)(‘%d) deduced by 8lGrZZ from measurements of the prompt y-ray spectrum resulting from 2-keV neutron capture in rseEu is in excellent agreement with the value S(n)(‘%d)=6240 keV 10 derived from the “%d(d,p) reaction, thus confirming the choice of reaction data (73Kr24 and 70Ma05) over the E data as the basis for deducing the Q(E) value for the decay of “‘Cd.

t The spectrometer energy calibration by 70Mu04 is based on the values given by 59Be51 for the Ka X-ray of Eu and Sm (73ScO4). These X-ray energies agree to within 0.2 eV with the values tabulated by 67Be73; however, the latest measurement of the wavelength of the Ka, X-ray in W (79KelO) indicates that the energies reported by 67Be73 and, therefore, al.so by 70Mu04 should be increased by approximately 0.0019%. The recalibrated Ey values are given in the level scheme and are listed in the tables. The listed uncertainties in Ey are those of 70Mu04.

The decay scheme shown in the drawings is from 74Se08. ‘ssGd-‘I,,,: from 72EmOl. ‘s3Gd-Q(s): recent work by 81GrZZ appears to remove the discrepancy between published values of

Q(E) for the ‘ssGd decay. 77WaOE adopted the value Q(c)=243 keV derived from measurements of the K-capture probability to the 172.85-keV level in IssEu, whereas 73Kr24 and 70Ma05 adopted the ‘ssGd(d,p) and ‘s4Gd(d,t) reaction Q values and adjusted the ‘s3Gd Q(c) value accordingly. The value for S(n)(‘=Cd) deduced by 81CrZZ from measurements of the prompt y-ray spectrum resulting from E-keV neutron capture in ‘ssGd is in excellent agreement with the value S(n)(‘ssGd)=6240 keV 70 derived from the ‘ssGd(d,p) reaction, thus confirming the choice of reaction data (73Kr24 and 70Ma05) over the c data as the basis for deducing the Q(E) value for the sdecay of ‘s3Gd. The newest mass adjustment yields 484.6 24 (82WaZZ).

Jr: there is some disagreement concerning the spin assignment

for this level. 72Ha41 and 75ZuZZ favor a 7/2+ assignment. 72Ha41 based this choice on their Ml multipolarity for the 325~ deduced from their measured a(K)exp. 77Al28 deduced E2 multipolarity for the 325~ from their measured a(K)exp and thus favor the Q/2 assignment. In the in-beam experiments of 78WiO2, the 325-keV level is interpreted as the Q/2+ member of the 7/X4041 band. The evaluator tentatively adopts the Q/2+ assignment.

p+,c Data from 153Tb c Decay 75Vy01,74TuOl

Sources produced by spallation of Ta by 660-MeV proton s and spallation of Gd by 120-MeV protons (75VyOl); by irradiation of natural Gd by 50-MeV protons (74TuOl), followed by chemical separation and mass separation. Other measurements: 78Cr02, 78Wa14, 76AI09, 75Sel6, 74Pe16, 68Ni04, 62Ha24, 61St15, 60Ab03, 59To26.

The decay scheme shown in the drawings is based on 75VyOi and 74TuOl. %p+=O.O63 9 (78Cr02).

80.8 I 80.8 Ey: from 61Dz04. Other measurements: 78 keV 5 (65Gr04), 80.9 keV (67Co20). 83 keV 8 (681001). The 80.8~ observed in the lS3Dy i decay is presumed to be the same y as observed in the IT decay. The ce-ce coincidence observed by 61Dz04 of the 80.8-keV and 82.SkeV transitions and the lifetime of the isomer suggest that the 163.3-keV level is the isomerie state, rather than the 80.8-keV level as suggested by 65Gr04. The 82.5-keV M2 transition is strongly converted and, therefore, was not reported.

7 Listed J values for band members are shown as tentative because of uncertainty in Jr assignments for bandheads. The AJ=l or 2 characters of the various bands are well establlshed by angular distribution measurements and observation of crossover transitions, but the Jn assignments of the bandheads are based on weak arguments and, consequently, must be regarded as tentative.

t hll/2-related band member. Angular distrlbutron results and observation of CI‘OSS~YBP transitions suggest AJ=l character for this band.

For absolute intensity per 100 decays, multiply by 0.0064 3. Transition is tentatively assigned to lJ3Dy t decay. Part of an unresolved multiulet. The listed intensity has been divided equally among the multiple placements. Listed values are those given by 77De05 deduced from Ice and Iy. Calculated from a(K)exp values of 77De05 unless otherwise indicated. Listed values are theoretical values from 68Ha53 for the listed multipolarities and mixing ratios.
