Atlas of nuclear isomers-Second edition

We present an updated version of the 2015-Atlas of Nuclear Isomers (Jain et al., 2015), compiling and evaluating experimental data for the isomers with half-life >= 10 ns, together with their spectroscopic properties such as excitation-energies, half-lives, decay modes, spins and parities, energies and multipolarities of isomeric transitions, along with the relevant original references in literature. The current version of Atlas presents many re-evaluated half-lives as compared to the 2015 edition, where values were referred to Nuclear Data Sheets publications, when no new data existed. The ENSDF database (Burrows, 1990), together with the XUNDL (XUNDL database, http://www.nndc.bnl.gov/ ensdf/ensdf/xundl.jsp) and the NUBASE2020 (Kondev et al., 2021) databases have been consulted for completeness, yet, data from original papers from journals were considered in the present evaluation, and the NSR bibliographic database (Pritychenko et al., 2011) has been searched to ensure that this work is as complete and current as possible. Several useful systematic features of nuclear isomers covered in this Atlas have been discussed. Literature cutoff date for the extraction of data is October 31, 2022.(c) 2022 Elsevier Inc.

Automated summary

This article presents an updated version of the 2015 Atlas of Nuclear Isomers, which compiles and evaluates experimental data for isomers with a half-life greater than or equal to 10 nanoseconds, along with their spectroscopic properties and relevant references. The current version includes re-evaluated half-lives based on new data and consultations with various databases.
