The process of plasma accretion onto a neutron star with a strong magnetic field is considered. It is assumed that a substantial part of the gravitational energy of the gas being accreted can be released as radiation in the accretion column at a distance of a few radii from the star. The theory is consistent with observations of the x-ray pulsar. Her X-1, and predicts that the pulsar would have a supplementary source of soft ..gamma.. rays at energies Eapprox. =150 keV.
