Quasiclassical expansion of the amplitude of potential scattering

V. N. Ostrovskii


Abstract: A simple method is proposed for calculating the corrections of higher orders in the expansion with respect to the quasielassical parameter of the angle-dependent amplitude of scattering on a spherically symmetric potential. The approach is based on the recently proposed representation of the complex deflection angIe for the amplitude. An explicit expression for the first-order correction is given.
