2023OG01 Phys.Rev. C 107, 054606 (2023) R.Ogul, A.S.Botvina, M.Bleicher, N.Buyukcizmeci, A.Ergun, H.Imal, Y.Leifels, W.Trautmann Isospin compositions of correlated sources in the Fermi energy domain NUCLEAR REACTIONS 40,48Ca(80Kr, X), E=35 MeV/nucleon; calculated isotope yield distributions of reaction products at forward angles with Z=1-4 (N=0-8) and Z=19-24 (N=19-31), neutron-to-proton ratio of the fragments, mean multiplicity of the fragments. 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.
