Scientific paper

A neutron superfluid in the inner crust of a neutron star is subject to drag forces which tend to bring the superfluid into corotation with the crust of the star. Here, results are presented from calculations of the drag due to the interaction of electrons with the charge that is induced around a superfluid vortex line by the long-range part of the nucleus-vortex interaction. For a large range of superfluid energy gaps and stellar temperatures, this drag force is larger than that derived by Feibelman (1971) for a different electron-scattering process. The present calculations give coupling time scales of months to years, which is too long to explain pulsar glitches or postglitch relaxations.
