| Popis: | Aligned fragment emission associated with peripheral and midperipheral dissipative collisions of {sup 124}Xe+{sup 124}Sn at E/A=50 MeV is examined. Binary decay of the excited projectile-like fragment (PLF*) is correlated with significant velocity damping from the projectile velocity. Both a forward emission component, attributed to standard statistical emission, and a backward component are observed. The backward component arises from both statistical and dynamical decay processes. This backward component manifests a strong alignment with the direction of the PLF* velocity and is found to depend sensitively on the atomic number of the light fragment, Z{sub L}, and the velocity of the PLF{sup *}. The yield of the backward component is significantly enhanced relative to the forward component. The composition of fragments emitted in the backward direction reveals that a correlation between alignment and neutron excess exists for fragments with Z |
