Abstract
It is shown that the approximation to the resonant solution of a Schrödinger equation, based on separable expansions of the asymptotically negligible part of the potential gives not only excellent resonance energies but also well-behaved wave functions even in large distances from the centre of the potential and even if relatively small bases are used.
