Abstract: The parameters E_R, Г_n and R^/ for ⁵²Cr resonance at the energy of 50 keV were determined from the set of the experimental average transmissions obtained by the shifting of average energy of the filtered neutrons. For E_R and Г_n parameters calculations, MCNP 4C code and own ROZPREG code were used. In the future, this code was taken as a basis for the new ROZPREGA program, which determined three parameters E_R, Г_n and R^/ for ⁵²Cr resonance. The obtained set of resonance parameters was compared with the results of other authors and data from the evaluated nuclear data libraries (ENDL).

Keywords: neutron transmission, resonance parameters, ⁵²Cr, filtered neutron beams, reactor.
