Transcription errors were introduced into Eqs. (20) and (21)of our paper; the functions Inm(J...) and Knm(±...), re-spectively, should be replaced by InmQ(F. .. ) and Knm(F . ).Another transcription error resulted in a term's beingdropped on the right-hand side of Eq. (23c); the correctedequation is

Knm(Q2 = 0) =-iCn(hL)6mi + i7KKn(h/L)6n-m,-1

(23c)

Finally, owing to printer's errors, incorrect characters ap-peared in Eqs. (13) and (17a): the character I should bereplaced by the German character S.
