Extract neutron-neutron interaction strength and spatial-temporal dynamics of neutron emission from two-particle correlation function

Dawei Si, Sheng Xiao, Zhi Qin +25

The neutron-neutron ($nn$) correlation function has been measured in 25 MeV/u ${}^{124}$Sn+${}^{124}$Sn reactions. Using the Lednický-Lyuboshitz approach, the $nn$ scattering length an…
