A systematic study of angular momentum dissipation in deep-inelastic heavy ion collisions is carried out by combining two experimental methods: the angular correlation of e particles and protons in coincidence with deeply inelastic light fragments; and the first two moments of the y-ray multiplicity. The unified analysis of these data, using a quantum mechanical treatment of the particle anisotropies and statistical decay calculations, yields most probable fragment spins 10=10.8_+l.lh and 13.4_+1.1h for 5SNi and 62Zn, respectively, close to the sticking limit. For the width of the vector spin distribution assumed in our analysis to be equal in all three directions we obtain a= 3.9• 1.3h and 2.9_+ 1.8h for 58Ni and 62Zn, respectively. These values correspond to most probable alignment parameters (P=)=0.66• and 0.82_+0.17 for 58Ni and 62Zn, respectively. As only very few partial waves of this light system undergo deep-inelastic scattering, a directly relates to spin fluctuations, and is compared to asymptotic values from transport theories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
