Abstract

The structure of the negative parity bands, based on the

ν h_{11 / 2}

orbital, in

{}^{129}{Ba}

is revisited to search for the wobbling mode in this nucleus. Existing angular distribution/correlation and linear polarization results are indicative of a large

E 2

admixture in the 365 keV interconnecting

Δ I = 1

γ

transition between yrast bands. This provides an indication of the existence of a wobbling mode in this nucleus. Theoretical calculations performed in this work using the quasiparticle plus triaxial rotor model have effectively replicated the available experimental results.

探索 Ba129 中摇摆运动的可能性

我们重新审视了 Ba129 中基于 νh11/2 轨道的负奇偶带结构，以寻找该原子核中的摇摆模式。现有的角度分布/相关性和线性偏振结果表明，在 365 keV 的相互连接的 ΔI=1 γ 转换中存在大量的 E2 掺杂。这表明该原子核中存在一种摇摆模式。这项工作利用准粒子加三轴转子模型进行的理论计算有效地复制了现有的实验结果。
