Impact parameter selected excited state populations for {sup 36}Ar+{sup 197}Au reactions at {ital E}/{ital A}=35 MeV

Impact parameter selected excited state populations were measured for {sup 36}Ar+{sup 197}Au reactions at {ital E}/{ital A}=35 MeV in order to better understand population inversions observed in a previous measurement of {sup 14}N+Ag reactions at {ital E}/{ital A}=35 MeV. The present impact parameter selected measurements revealed such population inversions to be most prominent in low multiplicity peripheral reactions. The excited state population for central collisions approach statistical model predictions for {ital T}{approx}4 MeV.
