ACCOUNTING OF TUNNELING EFFECTS WHEN CALCULATING THE ENERGY SPECTRUM OF THE SCHRÖDINGER EQUATION

Abstract

The general scheme of the method for integrating second-order differential equations in the form of power series is presented. The obtained results for the Schrödinger equation with potentials with two and three minima for quantum anharmonic oscillators are presented. The necessary accuracy of calculations is controlled by the number of terms in the power series and the number of digits in the mantissa of decimal numbers. The structure of the energy levels and wave functions are shown.
