Deuteron production and space-time characteristics of high-energy hadron-nucleus reactions

Abstract

The contribution of the coalescence mechanism to deuteron production is discussed on the basis of data on inclusive deuteron and proton production in hadron-nucleus interactions. The angular dependence and the A dependence of the coefficient of twonucleon coalescence into a deuteron are analysed for 7.5 GeV/c pA and 5 GeV/c rc-A interactions. The results suggest an elongated shape of the interaction region along the trajectory of the incident hadron and a successive knock-out of nucleons during propagation of the incident particle through a nucleus.

Inelastic electron-nucleus interactions at 5 GeV detected by ARGUS

“…In DINR the interaction region has effectively a shape of tube stretched along the direction of the incident particle momentum. It may be seen in hadron interactions with heavy nuclei [11,21,22]. Recently the tube-like shape of interaction region was also observed in the case of light nuclei.…”
