We show that the resonance wave function can be generally thought of as being unit normalized under an appropriate analytic continuation procedure and that, so normalized, the resonance eigenfunctions obtained from a finite-basis-set calculation can be used to evaluate partial widths. Numerical results are given for two model problems.
