Abstract

In the present work, we have predicted the half-lives for the β decay for higher forbidden unique transitions in the mass range of nuclei from A = 40-138. For these transitions, the experimental data for half-lives are not available except for a few cases. The calculations for half-lives are performed within the framework of the nuclear shell model (SM). We have used the effective interactions sdpf-mu, gxpf1a, gwbxg, G-matrix, snet, sn100pn, and jj56pnb to perform the SM calculations in different mass regions. A comprehensive discussion has been made between the SM predicted half-lives and the scaled half-lives from proton-neutron quasiparticle random-phase approximation (pnQRPA). The results of the present study will be useful to plan new experiments to measure half-lives for these higher forbidden unique β transitions.

高禁唯一β-衰变跃迁和壳模型解释
在本研究中,我们预测了原子核质量范围从 A = 40 到 138 的较高禁止唯一跃迁的 β- 衰变半衰期。对于这些跃迁,除少数情况外,没有半衰期的实验数据。半衰期的计算是在核壳模型(SM)的框架内进行的。我们使用有效相互作用 sdpf-mu、gxpf1a、gwbxg、G-matrix、snet、sn100pn 和 jj56pnb 来进行不同质量区域的 SM 计算。对 SM 预测的半衰期和质子-中子准粒子随机相近似(pnQRPA)的缩放半衰期进行了全面讨论。本研究的结果将有助于规划新的实验,以测量这些更高的被禁止的独特 β- 转变的半衰期。
