Projectile and Target Fragmentation in the Interaction of 12C and 27Al

Abstract

The emission of intermediate mass fragments (IMFs) produced in the inclusive 12 C+ 27 Al and 27 Al+ 12 C reactions at incident energies corresponding to a c.m. excitation energy of 107.5 MeV were studied at lab. angles of 12 • to 25 • . Double differential cross sections of the IMF spectra are compared to model calculations, which include direct breakup of both the projectile and target, nucleon coalescence, as well as partial and complete fusion. This study indicates the importance of the complementary nature of a reaction together with its inverse process in fully understanding the driving reaction mechanisms in the interaction of two light-mass nuclei.

New Results in Comprehensive Calculations of Heavy-Ion Interactions

“…Other results obtained within this approach, concerning the spectra of intermediate mass fragments (IMFs) emitted in the interaction between 12 C and 27 Al, are presented elsewhere [12]. The validity of the model must be confirmed by further studies; nevertheless the results discussed here and in [12] look encouraging.…”
