Possible chiral doublets in Ni

J. Peng (Department of Physics, Beijing Normal University, Beijing, China) ; Q.B. Chen (Physik-Department, Technische Universität München, Garching, Germany)

The open problem on whether or not the chirality exists in doublet bands M1 and M4 in light-mass even-even nucleus $^{60}$Ni is studied by adopting the recently developed fully quantal four-j shells triaxial particle rotor model. The corresponding experimental energy spectra, energy differences between doublet bands, and the available B(M1)/B(E2) values are successfully reproduced. The analyses on the basis of the angular momentum components, the azimuthal plots, and the K-plots suggest that the chiral modes exist at I12ħ in doublet bands M1 and M4.
