Study of the relaxation process induced by 80. 6 MeV /sup 16/O on /sup 27/Al

The decay parameters of the angular distributions, the charge distributions, and the first and second moments of the charge distributions with variation of TKEL are deduced from the results of the measurement of projectile-like fragments produced by 80.6 MeV /sup 16/O on /sup 27/Al. The relaxation process of this reaction is analyzed, and the effects of the potential energy surface on the first and second moments of the charge distributions are discussed.
