The angular distribution is calculated for a particle beam which has undergone both single scattering through a prescribed angle and multiple scattering. The usual assumptions are made: the target scatterers are immobile, and are homogeneously and randomly distributed, only binary collision events occur and the scattering has azimuthal symmetry, energy losses are negligible, and scattering angles are small in an absolute sense. The distributions are evaluated as power series for power-cross-section scattering, and in closed form for m = 12 and in the m = 1 (large-thickness or Gaussian) limit.
