Abstract
Noncentral collisions of projectiles with target nuclei at MeV are explored with an antisymmetrized molecular dynamics model. These collisions are found to be essentially binary in character with formation of an excited projectile-like fragment (PLF) and targetlike fragment (TLF). The average excitation energy deduced for the PLF and TLF saturates for midcentral collisions, fm, with its magnitude depending on the cluster recognition time. For short cluster recognition times , an average excitation energy as high as ≈6 MeV is determined, indicating a short statistical lifetime for the fragments produced. Evidence for such a rapid deexcitation is observed in the present calculations.
