摘要：

Nucleon self-energies from the pion-ring series are studied in the relativistic mean-field theory of linear sigma model with the omega meson and the DELTA. Near the Fermi surface of nuclear matter, the pion rings generate attractive scalar and vector potentials of 10-15% of the nucleon mass. These strongly energy-dependent potentials cause the nucleons to have a significant probability to be in a collective N-hole or DELTA-hole configuration.
