Nuclear three-body short-range correlations in coordinate space

NUCLEAR STRUCTURE 3,4He, 6Li, 16O; calculated three-body densities for the ground-state, contact ratios. Auxiliary-field diffusion Monte Carlo (AFDMC) method combined with next-to-next-to-leading-order (N2LO) local chiral interaction with the E1 parametrization of the three-body force.
