Triaxiality and alternating M1 strengths in f-p-g shell nuclei

Abstract

The appearance of alternating patterns in B(M1) strengths in f-p-g shell nuclei is surveyed. The M1 alternations in a sequence of N= 41 isotones, in conjunction with particle-rotor model calculations, is shown to provide information about changing {gamma} deformation. In addition to other odd-A nuclei, several odd-odd nuclei are shown to exhibit alternating B(M1) values and signature inversion. alternations have also been reported in a 4 quasiparticle band in {sup 86}Zr, where they have been interpreted in terms of the interacting boson model. (author). 15 refs., 1 tab., 6 figs.
