Momentum and Boltzmann distributions of neon fragments at∼300MeV/nucleon

Abstract
The interaction cross section of a neon beam at ∼300 MeV/nucleon along with the partial production cross sections of its fragments is studied in nuclear emulsion. Projected angular distributions of fragments are measured and are correlated with the longitudinal momentum distributions which enable us to estimate the Fermi momentum of the projectile. The space angle distributions of singly and doubly charged particles are discussed on the basis of the Boltzmann distributions.
