Betz, C.; Gzyl, H. Hitting spheres from the exterior. (English) Zbl 0793.60093 Ann. Probab. 22, No. 1, 177-179 (1994). Summary: By using an appropriate martingale, we compute the joint distribution of the hitting time and place of a sphere by \(d\)-dimensional Brownian motion, when the process starts outside the sphere.
