Abstract
In traditional nonrelativistic nuclear physics the nucleus is considered to consist of point-like nucleons interacting via NN forces which can be determined from NN scattering. About 30 years ago or so, however, other degrees of freedom were introduced into nuclear physics [245]. The sensational one of these was pion condensation (a transition to a state with a nonzero amplitude of the pion field), in which the energy of a pion becomes zero in nuclear matter owing to the interaction of the pion with nuclear medium, which also includes the delta isobar [246–249].
