Application of 3D WKB to scattering problems

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

In this work we present an extension of the 3D WKB approximation to include terms of orderh 2. This method can be easily implemented for scattering problems. We give a general prescription to calculate the crosssection up to the second order inh. As an illustration of the technique we calculate the cross-section for the Coulomb and the α/r2 potentials.
