Multiplicity ofγRays in the ReactionsKr86-Sn120andKr86-Er166

Abstract
The average γ-ray multiplicity M has been measured as a function of the scattering angle, energy loss, and nuclear charge of the projectile fragment produced in the Kr86-Sn120 and Kr86-Er166 reactions at a bombarding energy of 5.99 MeV/N. M increases steeply as a function of energy loss for the partly damped collisions but remains nearly constant for the fully damped events. M appears to depend mainly on energy loss rather than on mass transfer. The results are discussed in terms of a classical sticking model for the reaction mechanism.
