We extend former investigation of the transport of an energetic ions beam through a partially degenerate plasma. In the present work we investigate the electron contribution to the angular dispersion of the beam in the low velocity regime (ion beam velocity less than the average electron velocity). The multiple scattering contribution is implemented within the linear response function through an analytic and mean field interpolation of the target electron dielectric function between T = 0 (Lindhard) and T ≫TF (Fried-Conte). New simple analytical formulas are derived for the average scattering angle in the limiting cases of small and high temperature and also an interpolating formula is proposed at any degeneracy.
