WebAug 28, 2024 · The corresponding first passage time distribution is: F(t) = xf − x0 (4πDt3)1 / 2exp[ − (x − x0)2 4Dt] F (t) decays in time as t −3/2, leading to a long tail in the distribution. The mean of this distribution gives the MFPT τ = x2 f / 2D and the most probable passage time is x f2 /6D.
