Accuracy of Semiclassics: Comparative Analysis of WKB and Instanton Approaches

V. A. Benderskii, E. V. Vetoshkin, E. I. Kats

We analyze quantitatively the accuracy of eigenfunction and eigenvalue calculations in the frame work of WKB and instanton semiclassical methods. We show that to estimate the accur…
