Stylized features of single-nucleon momentum distributions

Understand

Nuclear short-range correlations (SRC) typically manifest themselves in the tail parts of the single-nucleon momentum distributions.

• We propose an approximate practical method for computing those SRC contributions to the high-momentum parts.
• The framework adopted in this work is applicable throughout the nuclear mass table and corrects mean-field models for central, spin-isospin and tensor correlations by shifting the complexity induced by the SRC from the wave functions to the operators.
• It is argued that the expansion of these modified operators can be truncated to a low order.
