“…It should be noted that the SRC effect may be also from other contributions such as tensor force [60][61][62][63][64], which is not presented in the EQMD model. The tensor force mainly acts on spin-triplet, isospin-singlet neutronproton pairs, and it significantly reduces the kinetic symmetry energy to even negative values at saturation density [65][66][67][68].…”

Short-range potential has been added into an extended quantum molecular dynamics (EQMD) model. The RMS radius, binding energy and momentum distribution of 12 C with different initial structures and short-range potential parameters have been checked. The separation energy of 12 C(p,2p) 11 B reaction is calculated and compared with the experimental data, it indicates that our modified EQMD model can be taken as a reliable tool for studying proton pair knock-out reaction. Furthermore, the short range correlation effects on emission time and momentum spectrum of two protons are discussed. Finally, the momentum correlation function of the emitted proton pair is calculated by the Lednicky and Lyuboshitz's analytical method. The result explains that short-range repulsion causes high momentum tail and weakens the momentum correlation function.
