Abstract

Lifetime measurements of the 5₁^-, 4₁^-, and 3₂^- levels in ¹⁴⁴Nd, coupled with measurements of the M1/E2 mixing of the 4₁^- → 3₁^- and 3₂^- → 3₁^- transitions, show that the transition strengths from these levas are in good agreement with those expected for quadrupole-octupole coupled states. Admixtures of the ν² (f_7/2i_13/2) quasiparticle configuration are the most likely explanation for the relatively large B(M 1:4^- > 3^-) value measured in the current work and the previously measured B(E5:5^- → 0⁺) value.
