Abstract

We derive an expression of the angle- and energy-integrated cross section σ1 for single inelastic collisions in nucleon-nucleus reactions. σ1 is related to the strength of the imaginary part of the optical potential. Using a phenomenological optical potential we calculate the ratio σ1R, where σR is the total reaction cross section. The ratio σ1R is about 50% for a target as light as 12C and drops to about 30% for a heavy target. The calculated values agree with experimental values for Al(p, p')X and Al(p, n')X at 90 MeV. Most of the single scattering cross section σ1 arises from partial waves which are located on the nuclear surface.
