Abstract
We suggest a closed form expression for the path integral of quantum transi tion amplitudes. We introduce a quantum action with parameters different fr om the classical action. We present numerical results for the harmonic osci llator with weak perturbation, the quartic potential, and the double well p otential. The quantum action is relevant for quantum chaos and quantum inst antons.
