**Abstract: **
The measurements of the P-even forward-backward correlation in the ^{35}(n, p)^{35}S reaction were carried out at resonance unpolarized neutrons of the IBR-30 pulsed facility. The alpha^{FB} values have been determined for neutron energy regions at averaged values of 3.1, 195 and 398 eV: (5.3\pm 7.6)\cdot 10^{-3}, (1.68\pm 0.50)\cdot 10^{-1}, and -(7.4\pm 3.6)\cdot 10^{-3}, respectively. Involving results of the experiment at thermal polarized neutrons on measurement of the P-odd and the P-even left-right correlations in given reaction, the weak matrix element has been estimated, and an analysis of the possible values of the neutron and proton amplitudes for channels with total momentum j=1/2 and 3/2 has been performed.
