Publications, 05 August 2021

We offer to your attention a preprint “Systematic of the Yrast-Bands in the Region of Heavy and Superheavy Even-Even Nuclei” P4-2021-15 published by the JINR Publishing Department. The authors are Efimov A. D.,

By using the extrapolation method, the estimations of yrast-band level energies for heavy and superheavy nuclei were obtained. For getting these estimations, the information about the properties of the neighboring nuclei was exploited. Such a method seems reasonable because for more collective states in the considered region of nuclei the yrast-band level energies varvary smoothly and slightly. The obtained results are very significant both for the experiment planning and for the analysis of the experimental data on the observation and study of the β-and γ-decays of high-spin isomers in the region of heavy and superheavy nuclei.

Sent to the Particles and Nuclei, Letters journal.

The investigation has been performed at the Flerov Laboratory of Nuclear Reactions JINR.
