Systematic shell-model study of Rn isotopes with $A=$ 207 to 216 and isomeric states

TL;DR

This paper conducts a comprehensive shell-model analysis of Rn isotopes from A=207 to 216, comparing calculated energies and properties with experimental data, and predicting unconfirmed states and isomeric configurations.

Contribution

It provides a systematic large-scale shell-model study of Rn isotopes using multiple interactions, including predictions for unconfirmed states and isomeric half-lives.

Findings

Calculated energies agree with experimental data where available.

Predicted spins and parities for several unconfirmed states.

Analyzed isomeric states and their configurations and half-lives.

Abstract

We present systematic large-scale shell-model calculations for Rn isotopes with $A=$ 207 to 216. For the $^{207-212}$Rn isotopes, we perform calculations with KHH7B interaction, while for $^{213-216}$Rn isotopes with KHPE and KHH7B interactions. The calculated energies and electromagnetic properties are compared with the available experimental data and predicted where experimental data are not available. We also suggest spins and parities of several unconfirmed states available from the recent experimental data. Comprehensive study of several isomeric states from the calculated shell-model configurations and half-lives is also reported.
