Theoretical Study on the Rotational Bands and Shape Coexistence of 179,181,183Au in the Particle-Triaxial-Rotor Model

摘要

@@ We perform a series of theoretical calculations and investigation for nuclei 179,181,183Au in the particle-triaxialrotor model with variable moment of inertia. The calculated energy spectra in 179,181,183Au agree well with the experimental data globally. The obtained results indicate that the nuclei 179,181,183Au have prolate deformation and involve shape coexistence with different deformation parameters in different bands. The main configuration of bands 1, 2, 3 and 5 in these nuclei are identified as [541]1/2- (πh9/2, α = 1/2), [541]1/2- (πh9/2, α = -1/2),[530]1/2- (πf7/2) and [660]1/2+ (πi13/2), respectively.
