For certain Lipschitz domains D we obtain a series expansion for the distribution of the lifetime τD of conditioned Brownian motion on D. From this we determine
$$\mathop {lim}\limits_{t \to \infty } {\text{ }}t^{ - 1} {\text{ }}log{\text{ }}P_x^h (\tau _D {\text{ > }}t) = \mathop {lim}\limits_{t \to \infty } {\text{ }}t^{ - 1} {\text{ }}log{\text{ }}P_x (\tau _D {\text{ > }}t) = {\text{--}}\lambda _D {\text{,}}$$
where λD is the first eigenvalue of 1/2 Δ on D.
