Abstract: We introduce a new characteristic of the penetration coefficient, the effective width of the barrier L, for the motion of Brownian particles through a potential barrier. In many instances of non-stationary transport this is a better characteristic of penetration than either the time lag or the steady-state permeability. Some brief comparisons between theory and experiments are made.
