Stopping relativistic Xe, Ho, Au, and U nuclei in nuclear emulsions.

Abstract

Nuclei of /sub 54/Xe, /sub 67/Ho, /sub 79/Au, and /sub 92/U accelerated at the Lawrence Berkeley Laboratory Bevalac to energies between 1200 and 900 MeV/n have been stopped in nuclear emulsions. The observed residual ranges have been compared with those calculated from various models of energy loss and shown to be most consistent with a calculation that includes those higher-order correction terms proposed previously to describe the energy loss of highly charged particles, for which the first Born approximation is not valid.
