Binary character of highly dissipativeBi209+136Xe collisions atElab/A=28.2 MeV

Abstract
Exclusive measurements of neutrons and charged products have been performed using a combination of 4π neutron and 4π charged-particle detectors. The maximum observed energy dissipation corresponds to only approximately one-half of the available kinetic energy. For any degree of dissipation, the velocity distributions of charged particles are characteristic of sequential emission following binary collisions. The data imply that central collisions also lead to bimodal emission patterns or that they are not sufficiently well isolated by the requirement of high particle multiplicities.
