Description
The isospin-dependent equation of state of nuclear matter, i.e. symmetry energy $E_{sym}(\rho)$ plays an important role in the study of nuclear physics and astrophysics. The calculation of transport model has shown the $E_{sym}(\rho)$ affects significantly the nucleon emission times in HIC, leading to significant variation of two-nucleon correlation functions.
Recent years, a compact spectrometer for heavy ion experiment（CSHINE）has been built, which has the ability to measure light charged particles, and the two charged particle correlation functions have been obtained. In this year, a neutron array with 212ps time resolution has been mounted on CSHINE[arXiv:2406.18605], and the neutron-neutron correlation function is measured in $25 MeV/u ^{124}Sn+ ^{124}Sn$. The effect of cross talk event on n-n correlation function has been analyzed. Finally, the scattering length, effective range, source size and timescale are obtained by Lednicky-Lyuboshitz model.
