Densities and momentum distributions in A≤12 nuclei from chiral effective field theory interactions

This study presents calculations of one- and two-body densities in both coordinate and momentum space for various nuclei up to ${}^{12}$C, using the phenomenological AV18+UX and various Norfolk $N\phantom{\rule{0}{0ex}}N$ + $N\phantom{\rule{0}{0ex}}N\phantom{\rule{0}{0ex}}N$ $\ensuremath{\chi}$EFT interactions. It features new calculations of the pair density as a function of both pair separation and center-of-mass, as well as the two-body momentum distribution for short- and long-range pairs differentiated by a pair separation boundary. The full set of results are available online for general use by the nuclear physics community and are intended to provide useful insights into the short-range structure of nuclei and various reaction processes.
