Abstract

Charge, mass
and isotopic distributions of fragments formed in the central collisions of
neutron poor and neutron rich elements ¹¹²Sn + ¹¹²Sn and ¹²⁴Sn
+ ¹²⁴Sn have been theoretically calculated and compared to the
experimental data. Influence of surface and symmetry terms on charge and
isotopic distributions, at low density freeze-out were investigated.  We show that significant reduction of the
symmetry term coefficient leads to better reproduction of the isotopic
distributions, while the surface term effect is negligible. This is in
agreement with our previous findings obtained from the interpretation of both
central and peripheral heavy ion collisions.

Keywords
