It is shown how matrix elements of the form \(\left\langle x\left|e^{-i f t}\right| y\right\rangle\), which arise in closed-form expressions for the generating functional, can be evaluated perturbatively using a path integral encountered in the quantum mechanics of a single particle. This allows one
