Certain aspects of the transverse-momentum distribution of fragments of relativistic 6Li nuclei in a nuclear emulsion
Lepekhin F. G., Seliverstov D. M., Simonov B. B.
A study has been made of the ratio of (a) the mean value of the observed transverse momenta of the fragments of the 6Li nucleus, with a momentum of 4.5 GeV/c per nucleon, in the interaction of this nucleus with emulsion nuclei to (b) the mean value of the transverse momenta of the fragments in the cm. frame of the two fragments. It was found that this ratio does not differ from the value fe) expected for the case of an independent emission of fragments. The size of the region in which the doubly charged fragments of 6Li are produced is about half the size of the region in which the fragment protons are produced. The Fermi momentum of the 6Li nucleus for protons is 111 ± 6 MeV/c. Evidence for the observation of an exchange of nucleons between the relativistic nucleus and the target is found. The corresponding cross section is стех= 12 ±6 mb.
