✦ Synopsis

The aim of this paper is to show how to compute the wave function of the ground state of a quantum mechanical system from the Euclidean path integral. The method is sufliciently general to encompass the case of degenerate classical minima, as well as the case of multidimensional systems. In the onedimensional case the WKB approximation is found in the forbidden region.
