摘要

在这项工作中，我们利用 KHH7B 和 KHM3Y 有效相互作用，对 A = 204-213 的 Bi 同位素进行了系统的壳模型（SM）计算。我们报告了与现有实验数据相对应的慢速和非慢速 SM 状态。通过与实验数据的比较，我们可以确定几个未经证实的态的自旋和奇偶性。我们还计算了电磁特性，并将其与现有的实验数据进行了比较，同时在没有实验数据的地方进行了预测。本研究还根据计算的 SM 构型及其各自的半衰期详细讨论了多种异构态。

Systematic shell-model study of structure and isomeric states in 204–213Bi isotopes

In this work, we have performed systematic shell-model (SM) calculations for Bi isotopes with A = 204–213 using KHH7B and KHM3Y effective interactions. We have reported yrast and non-yrast SM states corresponding to the available experimental data. From the comparison with the experimental data, we could assign spin and parity of several unconfirmed states. We have also calculated electromagnetic properties and compared them with the available experimental data and predicted where experimental data are not available. This study also includes a detailed discussion of multiple isomeric states based on computed SM configurations and their respective half-lives.
