Analisys of excitations in O from inelastic scattering of polarized protons of intermediate energy
M. S. Onegin
Comparison of the calculation of inelastic proton scattering from O with excitation of levels with with accessible experimental data at different energies of i…
UCN sources at external beams of thermal neutrons. An example of PIK reactor
E. V. Lychagin, V. A. Mityukhlyaev, A. Yu. Muzychka +5
We consider ultracold neutron (UCN) sources based on a new method of UCN production in superfluid helium (4He). The PIK reactor is chosen as a perspective example of the applicatio…
Unnatural-parity (p,p') reactions in a factorized impulse-approximation model for polarization transfer and spin responses
A. V. Plavko, M. S. Onegin, V. I. Kudriashov
Linear combinations of the complete polarization-transfer observables, Dij, in the (p,p') reaction at intermediate energies are demonstrated. A comparison between systematize…
Investigation of the fundamental constants stability based on the reactor Oklo burn-up analysis
M. S. Onegin
New severe constraints on the variation of the fine structure constant have been obtained from reactor Oklo analysis in our previous work. We investigate here how these constraints…
Experimental Neutron-Induced Fission Fragment Mass Yields of 232Th and 238U at Energies from 10 to 33 MeV
V. D. Simutkin, S. Pomp, J. Blomgren +9
Development of nuclear energy applications requires data for neutron-induced reactions for actinides in a wide neutron energy range. Here we describe measurements of pre-neutron em…
"Neutrino-4" experiment: preparations for search for sterile neutrino at 100 MW reactor SM-3 at 6-13 meters
A. P. Serebrov, A. K. Fomin, V. G. Zinoviev +20
There has been designed an experimental project "Neutrino-4" for 100 MW reactor SM-3 to test the hypothesis of the "reactor antineutrino anomaly". Advantages of the reactor SM-3 fo…
Ultra cold neutron trap as a tool to search for dark matter with long-range radius of forces
A. P. Serebrov, O. M. Zherebtsov, A. K. Fomin +1
The problem of possible application of an ultracold neutron (UCN) trap as a detector of dark matter particles with long-range radius of forces has been considered. Transmission of…
Dark Matter Accumulation near the Earth for the Long Range Forces case
M. S. Onegin, A. P. Serebrov, O. M. Zherebtsov
The accumulation of dark matter near the Earth is considered. We analyze the case of long range interaction forces. Additional density of the dark matter at the Earth's surface is…
Investigation of the fundamental constants stability based on the reactor Oklo burn-up analysis
M. S. Onegin
The burn-up for SC56-1472 sample of the natural Oklo reactor zone 3 was calculated using the modern Monte Carlo codes. We reconstructed the neutron spectrum in the core by means of…
Preparation of facilities for fundamental research with ultracold neutrons at PNPI
A. P. Serebrov, V. A. Mityuklyaev, A. A. Zakharov +13
The WWR-M reactor of PNPI offers a unique opportunity to prepare a source for ultracold neutrons (UCN) in an environment of high neutron flux (about 3*10^12 n/cm^2/s) at still acce…
Testing of various parametrizations of effective nucleon-nucleon interaction in elastic and inelastic scattering of polarized protons from C
M. S. Onegin, A. V. Plavko
The parametrization schemes of the effective nucleon-nucleon interaction proposed by Geramb and by Nakayama and Love are compared in their ability to reproduce the inelastic scatte…
Natural Nuclear Reactor Oklo and Variation of Fundamental Constants Part 1: Computation of Neutronics of Fresh Core
Yu. V. Petrov, A. I. Nazarov, M. S. Onegin +2
Using modern methods of reactor physics we have performed full-scale calculations of the natural reactor Oklo. For reliability we have used recent version of two Monte Carlo codes:…
