Abstract

A simple collective model is applied to understand the structure of the ΔI=1 doublet bands with the υh_<11/2>(×)πg_9/2 configuration in the doubly-odd nuclei, ^<98-104>Tc and ^<100-106>Rh. In the model, a doubly-odd nucleus is realized when there is one neutron in the 0h_<11/2> orbital and one proton in the 0g_<9/2> orbital, and the collective core represents the even-even part of the nucleus. The calculation reproduces the energy spectra and the ratios B(M1;I→I-1)/B(E2;I→I-2) for the doublet bands quite well. The analysis of the wave functions reveals new band structure, showing various angular momentum configurations of the neutron and the proton, weakly coupled with the quadrupole collective excitations of the core.
