Electrophoresis is often used to measure the "average" zeta (ΞΆ ) potential on particles. However, it has been found by previous researchers that in making predictions of colloidal forces and stability, the distribution of ΞΆ potential on the particles is important. This paper provides a straightforwa

Let Xt be a standard d-dimensional Brownian motion with drift c started at a ΓΏxed X0, and let T be the hitting time for a sphere or concentric spherical shell. By using an appropriate martingale, a Laplace-Gegenbauer transform of the joint distribution of T and XT is determined.
