Systematic study of forward-angle inclusive yields of nuclei with atomic numbers 8 < Z < 20 produced in nucleus-nucleus collisions of the 40Ar projectile on the 9Be target in the Fermi energy domain (36.5 A MeV) was carried out. The reaction products were measured by using the double achromatic fragment-separator COMBAS in the spectrometry mode at Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research (Dubna). Relative yields of isotopes were obtained and compared with the empirical parametrization of fragmentation cross section (EPAX), abrasion–ablation (AA) and available experimental data.

The longitudinal velocity and isotopic distributions of forward emitted fragments have been measured in the 11B (32.9 AMeV) + 9Be (27Al,197Au) reactions. The range of isotopes from Helium to Nitrogen has been observed. The particular interest of this experiment has been to investigate the influence of direct and dissipative processes on the fragment production for different targets. The fast velocity component characterized by a Gaussian shape is rather well described in the frame of simple statistical fragmentation model, but with smaller value of the width of the distribution. Isotopic and velocity distributions have been compared to Universal Parameterization model implemented in the LISE + + code. Increased yields of 4He and 7Li isotopes are observed as a possible influence of the cluster structure of the 11B nuclei on the total reaction mechanisms. [ABSTRACT FROM AUTHOR]
