Biography
Born June 5, 1970 in Moscow.
In 1993, he graduated from Moscow Engineering Physics Institute and joined the Kurchatov Institute .
From 1994 to 2004 he spent a long time abroad. In 1994-1998 and 2003-2004 he was a visiting scientist, then a postdoc at the University of the Mountains. Gothenburg , Sweden. There he received a PhD degree (1997, "Electromagnetic and weak interactions in light exotic nuclei"). In 1998-2001, he was a researcher at the University of Surrey (Great Britain). In 2001-2003 - a visiting scientist at the Institute of Heavy Ions ( German: Gesellschaft für Schwerionenforschung , GSI), Darmstadt, Germany.
Since April 2004, he resumed his work in Russia, at the G. N. Flerov Laboratory of Nuclear Reactions, JINR ; Since 2012 - Leading Researcher, JINR.
In 2006 - defended another, already “Russian”, candidate dissertation, topic: “Investigation of correlations in the spectrum of 5H superheavy hydrogen” [2] .
In 2009 - defended his doctoral dissertation, topic: “Dynamic aspects of the quantum-mechanical problem of several bodies near the boundary of nuclear stability” [3] .
In February 2016, she was awarded the honorary academic title of Professor of the Russian Academy of Sciences .
In October 2016, he was elected a corresponding member of the RAS .
Scientific activity
Specialist in the field of theoretical nuclear physics.
The author of 136 scientific papers, of which 4 reviews and 26 publications, letters.
In 2000, he developed a sequentially quantum-mechanical theory of two-proton radioactivity, the predictions of which were critical for the experimental detection of two-proton radioactivity (GSI, Germany, 2002), since they gave lifetimes 3 orders of magnitude more than generally accepted at that time. Lifetimes were successfully predicted for all currently discovered cases of 2p radioactivity (19 Mg, 45 Fe, 48 Ni, 54 Zn).
In 2005, he specified the role of “truly two-proton” decays and “soft” dipole excitations in the process of “fast” nucleosynthesis (r-process) at the border of proton stability.
In 2010 - developed and in 2015 - experimentally confirmed high-precision methods for solving the Coulomb three-body problem for decays of nuclear systems.
Developed methods for analyzing experimental data for three-particle decays of aligned systems populated in direct reactions (FLNR JINR, 2004). Currently, such a technique is used in the world only in the FLNR JINR.
Developed analysis methods required for experiments with fragment tracking. They allow one to determine the lifetimes of p or 2p decays in the range previously not available for measurements from picoseconds to tens of nanoseconds (GSI, Germany, 2007).
In 2011, he predicted the possibility of the existence of new types of radioactivity: two-neutron and four-neutron.
He is the coordinator of the scientific program of the ACCULINNA fragment separator in LNR JINR and the main author of the promising scientific program of the new ACCULINNA-2 separator fragment, which will be commissioned in 2016.
Conducts teaching activities as a professor at the Department of Theoretical Physics, Moscow Engineering Physics Institute.
