Statistical Multifragmentation Model (SMM) calculations using the ensemble method previously established for reactions at higher energy with relation to the nuclear liquid-gas phase transition. Inferred on the isotopic compositions of the projectile residues, the isospin exchange between the reaction partners, and the origin of the experimentally identified groups of Z=1-4 fragments and the neck-like emitted Z=2-11 fragments. Comparison to the data reported in 2021PI02: Phys.Rev. C 103, 014603 (2021). Obtained satisfactory reproduction of the experimental results with two correlated and statistically decaying sources, a projectile source and a neck source with enhanced neutron content.
