摘要

A triaxial projected shell model including configurations with more than four quasiparticles in the configuration space is developed and applied to investigate the recently reported five chiral doublets candidates in a single even-even nucleus Nd-136. The energy spectra and transition probability ratios B(M1)/B(E2) are reproduced satisfactorily. The configuration mixing along the rotational bands is studied by analyzing the intrinsic composition of the eigenfunctions. The chiral geometry of these nearly degenerate bands is examined by the K plot and the azimuthal plot, and the evolution from the chiral vibration to the static chirality with spin is clearly demonstrated for four pairs of partner bands. For bands D3 and D3-C, due to strong configuration mixing, their azimuthal plots show features of planar rotation and it is difficult to interpret them as chiral partners.
