The paper considers the problem of cyclotron line formation in a magnetic field of about 5 x 10 to the 12th gauss in the accretion column of a system such as Her X-1. Using a simple model for heating by the accreting matter, a kinetic equation is solved for the electron velocity distribution including terms for Coulomb collisions between thermal particles, and line and continuum emission. Significant departures from a Maxwellian distribution result in a lower line emissivity and reduced Doppler broadening of the line. The requirement of thermal stability of the atmosphere provides a range of allowed temperatures for the line emitting region. These results will be subject to modification when the effects of radiative transfer and radiation pressure are included.
