Abstract: The parameters ER, 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 ER and 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 ER, 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.
