Isospin fractionation in the nucleon emissions and fragment emissions in the intermediate energy heavy ion collisions

Jian-Ye Liu, Wen-Jun Guo, Yong Zhong Xing +1

The degree of isospin fractionation is measured by $(N/Z{)}_n$ / $(N/Z{)}_{N_{imf}}$, where $(N/Z{)}_n$ and $(N/Z{)}_{N_{imf}}$ are the saturated neutron-proton ratio of nucleon emissi…
