Angular-Momentum Transfer in Deep-Inelastic Processes

$\gamma$-ray multiplicities have been measured as a function of fragment $Z$ both for the relaxed and quasielastic component in the reaction of 175-MeV ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ on ${}_{}{}^{\mathrm{nat}}{}_{}{}^{}\mathrm{Ag}$. Evidence for maximum transfer of orbital angular momentum to rotation of the fragments is seen at 90° for the relaxed component, indicating a rigid rotation of the intermediate complex. Possible evidence for angular-momentum transfer via mass transfer and other mechanisms are discussed for the quasielastic component.
