The Institute of Nuclear Physics

Ministry of Energy of the Republic of Kazakhstan

Laboratory of theoretical nuclear physics

The Laboratory for Theoretical Nuclear Physics was established on December 1, 1987 on the initiative of Dr. Sci. Nurgali Zhabagayevich Takibaev, who became it until 2004, the next years the laboratory of the planet, Doctor of Physical and Mathematical Sciences, prof. Elena Tuleubekovna Ibraeva. Currently, the head of the laboratory is Doctor of Physical and Mathematical Sciences, Fedor Mikhailovich Penkov.

Direction of research

Laboratory staff have classes in the areas of “Theoretical and Mathematical Physics” and “Theoretical Nuclear Physics”. The scientific interests of the laboratory from the day of its foundation are associated with accurate descriptions of systems of a small number of bodies at low energies. With the arrival of E.T. Ibraeva added to these problems the problems of diffraction scattering of hadrons by light nuclei. Laboratory staff actively participate in the work of local and international scientific programs and experimental collaborations, work on the topics of State scientific and technical programs, grants from the Ministry of Education and Science of the Republic of Kazakhstan and ISTC.

International scientific relations

The authors’ collectives of publications of the laboratory staff will include co-authors from JINR (Dubna), SRINP TPU (Tomsk), SRINP MSU (Moscow), FIAN (Moscow), University of Bonn (Bonn) and other scientific centers. The results of the work are presented many times at international conferences.

Main scientific achievements:

The effective interaction of a neutron with a deuteron was obtained in the framework of an exact formulation of the three-body problem (1988-1992).
The Efimov resonances are found before the breakup threshold of three-particle systems (1991-1995).
Found and studied Efimov and quasi-Coulomb bound and resonance states in molecular systems (1996-2000).
The lifetimes of resonances in mesomolecular systems and the rates of nuclear transitions (1996–1998) have been calculated.
The phenomenon of resonant “quantum transparency” of the probability of the passage of composite particles through the barrier (1999-2006) was discovered.
Found the contribution of the resonant transparency of the barriers for compound particles in the physical observables (2012-2015).
The contribution of channeling effects to an increase in the yields of products of nuclear capabilities at ultra-low energies (2012-2015) is determined.
A systematic description of elastic and inelastic scattering of hadrons by light nuclei in the theory of Glauber’s theory (1994–2002).
The experimentally observed effects in the scattering of hadrons by light nuclei at high energies (1997–2002) are explained.
The influence of the structure functions of neutron-rich nuclei on the scattering characteristics: differential cross section and vector analyzing power (2001-2008) has been clarified.
