Abstract:

Effects of both the static and the dynamic triaxial deformations on the signature dependence of B(M1) and B(E2) in odd-A nuclei are studied by applying the RPA formalism based on the rotating shell model to odd-A nuclei. Numerical examples are presented for ¹⁶⁵Lu and ¹⁵⁷Ho. The observed M1 properties of the high-spin region of ¹⁶⁵Lu are well reproduced, while the extremely strong signature dependence of B(E2) in ¹⁵⁷Ho is not reproduced by the calculation.
