【报告摘要】

We study the double gamma-decay of the quadrupole state of an even-even spherical nucleus. An influence of the phonon-phonon coupling on the double gamma-decay width is analysed within the quasiparticle-phonon model based on the Skyrme energy density functional. It is shown that the double gamma-decay width is sensitive to the interaction of the one- and two-phonon configurations of the giant dipole resonance.

Professor Alexey Severyukhin is a Senior Researcher at the Bogoliubov Laboratory of Theoretical Physics (BLTP), Joint Institute for Nuclear Research (JINR) in Dubna, Russia. He is an expert in microscopic nuclear models, energy-density functional theory, random phase approximation, generator coordinate method, and random matrix theory, with which he studies low-energy vibrational excitations, giant resonances, Gamow-Teller resonances, beta-decay, beta-delayed neutron emission. Prof. Severyukhin has received many awards for his contributions, including the First Prize in Experimental Physics from JINR in 2017, as well as the Blokhintsev Prize for Young Scientists in 2008 and 2009. As a member of organizing committee, he organized the “LXXIV International conference Nucleus-2024: Fundamental problems and applications" and the "International School on Nuclear Theory and Astrophysical Applications" at JINR.
