Abstract
The variational perturbation theory for wave functions, which has been shown to work well for bound states of the anharmonic oscillator, is applied to resonance states of the anharmonic oscillator with negative coupling constant. We obtain uniformly accurate wave functions starting from the bound states.

10 pages, RevTeX, 4 ps figures. There were some calculational mistakes in the previous manuscript. The correct results obtained by our method show excellent agreement with the exact solutions
