Abstract

The first results of the measurement at 0 degree of the cross-section ration Rdp = 0.50 +/- 0.02 in charge exchange (np) reaction on H2 and D2 targets at the neutron beam kinetic energy 1.0 GeV are presented. As a result the value 0.33 +/- 0.03 of the ratio of non spin-flip to spin-flip contribution in np-pn charge exchange at 0 degree was obtained.
