Abstract

In the present paper we study the structure of the WKB series for the polynomial potential V(x)=xNV(x)=x^N (NN even). In particular, we obtain relatively simple recurrence formula of the coefficients \sk\s'_k of the semiclassical approximation and of the WKB terms for the energy eigenvalues.
