Extracting Neutron-Neutron Interaction Strength and Spatiotemporal Dynamics of Neutron Emission from the Two-Particle Correlation Function

Author(s): Dawei Si et al. The neutron-neutron ($nn$) correlation function has been measured in $25\text{ }\text{ }\mathrm{MeV}/\mathrm{u}\text{ }^{124}\mathrm{Sn}+^{124}\mathrm{Sn}$ reactions. Using the Lednický-Lyuboshitz approach, the $nn$ scattering length and effective range (${f}_{0}^{nn}$, ${d}_{0}^{nn}$), as well as t… [Phys. Rev. Lett. 134, 222301] Published Thu Jun 05, 2025
