Cross-magnetic-field transport due to like-particle collisions is discussed for the parameter regime λDrL, where λD is the Debye length and rL is the characteristic Larmor radius of the colliding particles. A new theory based on collisionally produced E×{}B drifts predicts a particle flux which exceeds the flux predicted previously, by the factor (λDrL)²1.
