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.eninfo:eu-repo/semantics/openAccessArticle113116
