N2 - The two components of the complex escape time τesc(k) = τesc1(k) - iτesc2(k) for an electron from a localised state in a one-dimensional disordered system are shown to be connected by Kramers-Kronig integral relations. In the complex k plane, τ1 and τ2 form an elliptic contour. Component τesc2(k), in the case of an opaque barrier at an energy close to the bound level in the well, coincides with the lifetime expression.
