Isospin effects on two-particle correlation functions in intermediate energy heavy ion reactions

摘要

Exclusive data from an intensity interferometry experiment are presented, where, for the first time, the technique of two-nucleon correlation functions is applied to isotopically selected data, with the aim to study the isospin dependence of the nuclear equation of state (EOS). The different correlation function strength, observed for two isotopically separated systems, E/A=61 MeV ~(36)Ar+~(112)Sn, ~(124)Sn, is not explainable in terms of system size, and is attributed to the different isospin content. This experimental finding supports theoretical predictions based on isospin dependent transport models, and demonstrates that intensity interferometry is a promising tool to study the isospin dependence of the EOS.
