Application of the New Form of the Semiclassical Quantization Condition
  We demonstrate how a certain new form of the quantization condition proposed earlier can be used outside the class of potentials for which this form ensures exact spectra. Taking this form as a base we get an improved interpolating condition for the potential wells with coinciding an + and - infinities asymptotical values. Accuracy of the above conditions is discussed.
