Systematic shell-model study of $^{98-130}$Cd isotopes and $8^+$ isomeric states

TL;DR

This study uses shell-model calculations to analyze the energy spectra and electromagnetic properties of Cd isotopes from $^{98}$ to $^{130}$, predicting unconfirmed states and examining $8^+$ isomers.

Contribution

It provides a systematic shell-model analysis of Cd isotopes with a realistic interaction, including predictions for unconfirmed states and isomer properties.

Findings

Calculated spectra agree with experimental data

Predicted spins and parities for unconfirmed states

Analyzed properties of $8^+$ isomeric states

Abstract

We present systematic shell-model studies of even-even $^{98-130}$Cd isotopes using a realistic effective shell-model interaction derived from the G-matrix approach with an inert core $^{88}$Sr. Our calculated low-lying excited energy spectra and electromagnetic properties are compared with the experimental data. On the basis of recently available experimental data, we predict spins and parities corresponding to unconfirmed states. We also discuss the properties of $8^+$ isomeric states in $^{98-104,130}$Cd isotopes.
