Solution of variable phase equation with singular potentials by means of formal series

A. A. Atanasov


Abstract: The method of formal series is applied to the solution of a variable phase equation with singular potentials. The limiting cases of scattering at high and low energies and the problem of resonances with a singular potential at a finite point are considered.
