Resum:	Consider 3dimensional Brownian motion started on the unit sphere { $x $ = 1} with initial density ρ. Let ρt be the first hitting density on the sphere { $x $ = t + 1}, t > 0. Then the linear operators Tt defined by Tt ρ = ρt form a semigroup with an infinitesimal generator which is approximately the square root of the Laplacian. This paper studies the analogous situation for Brownian motion with a drift b, where b is small in a suitable scale invariant norm.
