Progress in a research program on theoretical physics is reported. A study was made of Coulomb scattering of polarized electrons in which an analytical expression for the spin-dependent cross sections for this type of scattering valid to order ( alpha Z)/sup 4/ was developed. In other activities, the radiative corrections to the Mott scattering asymmetry function are being evaluated to reconcile theoretical and experimental values. By use of a modified SommerfeldMade wave function for the electron and (initially) an exact Muon K- shell, an accurate evaluation of the Coulomb field effects on the decay of a polarized muon from the K-shell of mu atoms was made. A relativistic scattering wave function which is valid to second order in the alpha Z for all electron velocities was obthined. The cross section for bremsstrahlung production at short wave limits of the spectrum was evaluated to terms of relative order alpha /sup 2/Z/sup 2/2 for high energy incident electrons. An alternate form for the exact continuum state relativistic Coulomb wave function was developed which expresses the spin dependence in terms of the usual Dirac plane wave spinor. (J.R.D.)
