The ion distribution function over transverse velocities and the ion heating efficiency (which is defined as the fraction {eta} of ions heated above a certain energy W{sub min}) are calculated in the context of a plasma method for isotope separation on the basis of ion cyclotron resonance heating. The ion distribution function over longitudinal velocities is assumed to be linear in the range of low velocities. It is shown that, when the ions are heated to high energies, the averaged ion distribution function over transverse velocities becomes highly nonequilibrium and has two peaks. Results are presented from calculations of the ion heating efficiency {eta} for W{sub min} = 40 eV and for different values of the parameter p that characterizes the ratio of the wavelength {lambda} of the antenna electric field to the length L of the heating region. The relative roles of the time-of-flight and the Doppler broadening are analyzed, and the separation parameters of a collector of heated ions are estimated.
