In this paper we present results of computations for the ground energy of weakly coupled double well potential in quantum mechanics. We give a numer-ical evidence for cancelation of imaginary contributions to energy coming from Borel resummation and multi-instanton terms. We also estimate several higher coefficients of the multi-instanton expansion which are not given in the literature.
