Measurement of energy emission from O+A and p+A collisions at 14.5 GeV/c per nucleon with a lead-glass array

Description

The first data from a 16O beam of total energy 232 GeV at the BNL Tandem-AGS are reported. A lead-glass array covering the laboratory pseudo-rapidity interval 1.25 < η < 2.44 recorded the energy emitted from 16O interactions in Au, Cu, and Mylar and from proton interactions in Au. The shapes of the energy spectra imply that a nucleon loses most of its energy in the first few collisions. Consequently a simple description of the observed 16O+Cu and 16O+Au spectra as a properly weighted convolution of the observed p+Au spectrum is obtained. It is shown that 16O nuclei at this energy can be substantially stopped by nuclei of the size of Cu. An estimate of the energy density for central collisions is given. (orig.)
