How to extend Chart of Nuclides?

News, 09 April 2021

In the journal Nuclear Physics News for the 4th quarter of 2020, an article was published by Gurgen Adamian and Nikolai Antonenko, employees of the Bogolyubov Laboratory of Theoretical Physics, in collaboration with Alexis Diaz-Torres (University of Surrey) and Sophia Heinz (GSI, Darmstadt and the University of Giessen). This journal is published four times a year by the Nuclear Physics European Collaboration (NuPECC) and provides an overview of the most significant achievements and key conferences.

The article describes the main methods of extending the map of nuclides in a popular form. Currently, more than 3,000 isotopes of 118 elements are known. The theory predicts the possibility of the existence of about 4,000 more isotopes, which can be obtained in the reactions of fragmentation, fission, fusion, and multi-nucleon transfers. Moreover, only the last two types of reactions can be used for new isotopes of transuranium elements. It is expected from theoretical estimates that about 200 new transuranium nuclides can be synthesized in these reactions. The research described in the article is closely related to the experimental programme of FLNR JINR.
