摘要：
We study the effect of pion condensation on the energy gap of superfluid neutron matter. The neutron energy spectrum is determined in a Walecka-type model in the mean-field approximation. This spectrum is inserted into the BCS model to calculate the energy gap for singlet pairing superfluid neutron matter. With this procedure we calculate the energy gap for pion condensed and normal matter at various densities. It turns out that in the superfluid density region thc pion condensation is too weak to modify the energy gap significantly.
