Description
A procedure is presented for finding simple approximations of the discrete eigenvalues of the Zakharov-Shabat scattering problem corresponding to the nonlinear Schroedinger equation. The approximation is in the form of an interpolation formula which combines results for small eigenvalues, obtained by a direct variational approach, and for large eigenvalues, obtained by the Bohr-Sommerfeld quantization rule.
