Main Achievements
The principal results of experimental works carried out at the reactor of PNPI are
connected with the discovery and study of parity non-conservation in nuclear
transitions and fission, the search for the neutron dipole moment, the precision
measurement of the lifetime of a neutron, and the study of the asymmetry of its
beta-decay.
In solid state physics important results were received in the investigations of the HTSC
and magnetics structure on the atomic level. The spin dynamics of phase transitions
was studied by the use of polarized neutrons, the critical scattering from the threespin
correlations and the inelastic scattering asymmetry with the magnetic field
present were revealed exerimentally.
The technique of crystal-diffraction spectroscopy of high resolution, with the help of
which in PNPI first-class results were received in nuclear spectroscopy and solid
state physics, made it possible to pass over the study of the particle channeling
effect and to use it in accelerator technology and high energy physics.
The nucleon- and pion-nucleon scattering, the spatial and momentum nucleon
distributions in nuclei and the properties of nuclei far from the line of beta-stability
were studied experimentally at the synchrocyclotron. The results of theoretical and
experimantal studies of the process of hydrogen isotopes muon catakyzed fusion
advanced PNPI into a number of world leaders in this field. At the medical tract of
the synchrocyclotron more than 1000 patients were put through the proton
stereoactic treatment.
The theoretical study results of the behavior of hadron interaction amplitudes, the
pertubative and non-pertubative QCD, the extended standard electroweak model,
the self-consistent methods in the theory of complex nuclei and heavy atoms, the
description of P- and T- odd effects in atoms and molecules are also generally
recognized.
The determination of the details of the protein biosynthesis mechanism, the elaboration
of the diagnostic methods of human hereditary desease, the creation of biological
test-systems for ecological monitoring are the results of biological active
macromolecules and cell structures research in PNPI.
