Rigid Rotation andl-Wave Fractionation in the Deep-Inelastic Reaction: 664-MeVKr84+Agnat

Out-of-plane angular distributions have been measured for sequential $\alpha$-particle decay from targetlike fragments produced in fully damped heavy-ion collisions. Fragment spins, extracted from the angular distributions, and $\gamma$-ray multiplicity data are consistent with rigid rotation of an intermediate complex composed of two substantially deformed spheroids. Over the limited range of asymmetries populated, $l$ fractionation appears to play a minor role.
