Abstract

We have measured the production of charged nuclear fragments in collisions of 1.05 GeV/nucleon and 2.1 GeV/nucleon proton, deuteron, alpha, and carbon projectiles as well as 0.4 GeV/nucleon alpha particles on targets of C, Cu, Pb, and H (from a CH2—C subtraction), using a double focusing spectrometer. We present single particle inclusive cross sections for the production of Z=1 and Z=2 fragments in the region 0.5(pZ)lab8.7 GV/c and 0°ϑlab12°. We discuss the relevance of the concept of limiting fragmentation to our data and point out possible uses of the data to study nuclear structure and particle production mechanisms. A detailed comparison is made with Glauber-type models and hard-scattering models as well as the coalescence model.
