Abstract
The threshold density for pion condensation in neutron matter is determined with a model including nuclear interactions and the resonance in -nucleon scattering. Depending on the magnitude of correlations, pion condensation can have a threshold as low as 0.1 neutrons/ or not occur at all. Applying the model to nuclear matter, we find that in the absence of correlations physical pions have a very large effective mass. With correlations, these effects are diminished, but pion condensation could still occur at twice normal nuclear matter density.
