Nuclear structure of Xe-Pt nuclei in the framework of ARM and odd-even staggering

Abstract

The asymmetric rotor model (ARM) of collective rotation is used to search for the correlation between the rotational energy with the asymmetric parameter \gamma_0 for Xe-Pt nuclei. The correspondence of the ratio ROTE/E(2_1^+) vs. R_{4/2}(=E(4_1^+)/E(2_1^+)) and \gamma_0 is used to distinguish between the axially symmetric and triaxial nuclei. The correlation between deformation parameter \beta and \gamma_0 is studied to understand the structure of the nuclei. The \gamma-band energy staggering in low-spin, low-energy spectra of even-even ^{122-124}Xe and ^{124-128}Ba nuclei is also discussed. We have compared our results with experimental data and other theoretical models.
