Short-range correlations and momentum distributions in mirror nuclei 3H and 3He

Abstract

Motivated by recent high-energy electron and ${}^3\mathrm{H}$ and ${}^3\mathrm{He}$ nuclei scattering experiment in Jefferson Lab (Nature 609, 41 (2022)), the short-range correlations (SRCs) between nucleon pairs for 3-nucleon systems are microscopically studied using realistic $NN$ 2-body interaction and two-Gaussian type $NNN$ 3-body interaction. The wave functions of both ${}^3\mathrm{H}$ and ${}^3\mathrm{He}$ are obtained by solving 3-body Schrödinger equations using Gaussian expansion method (GEM). The differences of one-nucleon and nucleon-nucleon momentum distributions between ${}^3\mathrm{H}$ and ${}^3\mathrm{He}$ are analyzed in detail. The results show that the percentages of $pn$-SRC pairs are significantly enhanced as compared with those of $nn(pp)$-SRC ones in ${}^3\mathrm{H}$ and ${}^3\mathrm{He}$ nuclei, which is consistent with the experimental findings.
