Description

Recent advances in the study of the short-range structure of nuclei indicate that about 25% of nucleons in medium to heavy nuclei have momentum greater than Fermi momentum (k > kF). These high-momentum nucleons are found to be predominantly short-range correlated proton-neutron pairs, created by the short-range tensor interaction. Since these high momentum nucleons significantly increase the average kinetic energy on nucleons in symmetric nuclear matter but not in pure-neutron matter, they should decrease the value of the kinetic part of the nuclear symmetry energy. In this talk I will review results from recent studies of correlations in nuclei and and their potential implications on astronomical object denser than nuclei.
