[en] A form-factor in the expression for a absorbed power of resonance particles in a tokamak during cyclotron heating at ωΩsub(Ca) is calculated. Evaluations for possible mechanisms of radiative transfer, arising due to cyclotron wave-particle interaction, are obtained. It is pointed to possible concentration of particles near a resonance zone, that is the reason for plasma polarization and occurrence of a poloidal electric field. The ''neoclassical'' ion flow evaluations obtained in the presence of this field can apparently explain the observed difference in particle confinement while icr and ecr plasma heating in the tokamak
