Beta Decay

Gamma Decay

The total angular momentum change, L in a nuclear transition can take the values |Li − Lf | ≤L ≤ |Li + Lf |, L>0This is also subject to selection rules for the parity difference between initial and final states: P = (−1)L, for electric transitionsand P = (−1)L−1, for the (even further suppressed) magnetic transitions. Here are some examples: 2+ → 1−(E1)2+ → 1+(M1)3+ → 1−(M2)3+ → 1+(E2)
