Abstract
Let $X$ be the Brownian motion process in $\mathbb{R}^d, d \geqslant 3$ with $X(0) = 0$. Let $L_r$ be the last exit time of $X$ from the ball of radius $r$ centered at the origin. Then $(L_r)$ has independent increments and we compute the distribution of $L_r$. When $d = 3$ this yields a simple proof of a recent result of Pitman.
