We consider a stationary nonlinear Schroodinger equation with a repulsive
delta-function impurity in one space dimension. This equation admits a unique
positive solution and this solution is even. We prove that it is a minimizer
of the associated energy on the subspace of even functions of $H^1(\R, \C)$,
but not on all $H^1(\R, \C)$, and study its orbital stability.
