• The drift velocity of particles undergoing E^^^→×B^^^→ rotation in a collisional plasma is investigated by test wave technique and Langmuir probe. The velocity determined by probe is corrected by including effect of cylindrical geometry and finite Larmor radius effect. From the B dependence of the corrected velocity and the drift velocity determined by test wave, the ion-neutral collision cross section is determined which is found to be in disagreement with the value given by the current data. This disagreement is attributed to an inappropriate collision cross section at low energy at which small angle scattering events are frequent. It is proposed that in events in which there is a loss of particle drift velocity, we should use the so-called "slowing down cross section"σ_s, rather than the total cross section.
