Summary

In this work we present an extension of the 3D WKB approximation to include terms of orderh2. 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.
