Abstract
The generalized WKBJ method is used to study the phase shifts of the radial wave functions of ultrarelativistic electrons scattered by a central field. The scattering phases are derived for ultrarelativistic electrons within terms of second order in ħ inclusively; the relations found for the scattering phases are more general than the familar Rosen-Yennie expressions.
