摘要

The linear version of the variable-phase approach in the theory of potential scattering is supplemented with a new asymptotic method. This method is intended for performing a quantummechanical analysis and for constructing explicit low-energy approximations for partial-wave phase shifts and radial components of the wave function for the scattering of a quantum particle on a central short-range potential. The procedure used to construct all low-energy approximations reduces to solving a recursion chain of energy-independent sets of equations, each such set consisting of two linear first-order differential equations.
