The dispersion and spatial damping of Whistler waves propagating in plasma columns having relatively high electron density and moderate electron temperature are investigated theoretically and experimentally. In collisionless hot plasmas, the damping rate k_i, wavenumber k_r and the ratio k_i/k_r as functions of frequency ω are derived in the vicinity of the cyclotron resonance. When the effects of collisions become significant, the above quantities are corrected by including the collision frequency ν appropriately. Near the resonance, k_i/k_r equal to the sun of the cyclotron damping term and the collisional damping term which is proportional to ν/ω_c. The observed dispersion curves agree well with those in collisional hot-plasma theory. the observed damping rate is due to the cyclotron damping plus Coulomb collisional damping in moderate T_e plasmas, while it is ascribed totally to Coulomb collisions in low T_e plasma.
