Data on the production of positively charged particles emitted at an angle of 40
(in the laboratory frame) with transverse momenta of up to 2.7 GeV
in the interaction of 50-GeV
protons with carbon, aluminum, copper, and tungsten nuclear targets are presented. Particular attention is given to studying the production of light nuclear fragments, such as deuterons (
) and tritons (
). An analysis of data on
and
particles gives grounds to state that these fragments arise via a local mechanism of their direct knockout from nuclei. The results were obtained in the SPIN experiment at the Institute for High Energy Physics (IHEP, Protvino).
