Abstract: (Elsevier)
The application of the Brueckner theory to the nuclear many-body problem can be greatly simplified if one separates the two-nucleon interaction (for any given state and relative momentum) into a short range part v s and a long range part v l . The cut is made such that v s alone gives no phase shift for free particle scattering. If the separation is made in this way, then the presence of nuclear matter, as manifested by the Pauli principle, has only a small effect on the two-particle wave function at short distances. On the other hand, the Pauli principle drastically reduces the induced correlations due to v l . In fact, v l is the first approximation to the effective interaction in nuclear matter. This procedure permits one to systematically expand the effective interaction in terms of t s , the reaction operator for free particles caused by v s alone.References(49)
