The instability of a plane boundary of Plasma supported under gravity by a magnetic field is investigated in the first order orbit theory taking into account the collisions between charged and neutral particles, where the collision frequency is assumed to be small as compared with the Larmor frequency. It is demonstrated that the instability growth rate may be suppressed by collisions of ions with neutral particles, and the physical mechanism of the stabilization is the "discharge" of surface charges as a result of the collisional drift motion of ions which takes place across the magnetic field in the direction of the produced electric field. The results are applied to the slow theta-pinch experiments in order to understand the observation of no Rayleigh-Taylor instabilities in the contraction stage of the slow theta-pinch.
