Coulomb logarithm accuracy in a Yukawa potential

Abstract:
We present a complete theory of the scattering of a particle in a Yukawa potential when the screening length is much larger than the classical impact parameter for 90^{∘} deflection and than the de Broglie length. The classical limit, the quantum limit, and the intermediate case are investigated, enabling an accurate determination of the argument of the Coulomb logarithm in the general case. The connection with previously published results is made.
