Extended Data Fig. 6: Nuclear contacts values.
From: Many-body factorization and position–momentum equivalence of nuclear short-range correlations

The extracted contact values have been divided by A/2 and multiplied by 100 to give the percent of nucleons above kF. For symmetric nuclei, Cnns=0 = Cpps=0. In the case of 3He, Cnns=0, as there is only one neutron in this nucleus. In the case of 3H, Cpps=0, as there is only one proton in this nucleus, and the values shown under Cpps=0 correspond to Cnns=0.
