Using the off-shell model for ..pi..N scattering based upon current algebra and a dispersion-theoretical axial-vector nucleon amplitude dominated by the ..delta.. (1230) isobar, we investigate the critical density for the onset of pion condensation in the neutron matter. We find that condensation occurs at approximately nuclear-matter density assuming nucleon-nucleon correlations are neglected. The repulsive nature of the latter should presumably push up this critical density.
