英文摘要:
The positive-parity doublet bands based on the pi h(11/2)circle times nu h(11/2) configuration in Cs-126 were investigated in the two quasiparticles coupled with a triaxial rotor model. The energy spectra E(I), energy staggering parameter S(I)=[E(I)-E(I-1)]/2I,B(M1) and B(E2) values, intraband B(M1)/B(E2) ratios, B(M1)(in)/B(M1)(out) ratios, and orientation of the angular momentum for the rotor as well as the valence proton and neutron are calculated. After including the pairing correlation, good agreement has been obtained between the calculated results and the data available, which supports the interpretation of this positive-parity doublet bands as chiral bands.
