Abstract. In the paper we investigate tangential boundary limits of invariant Green potentials on the unit ball B in C", n i> 1. Let G(z, w) denote the Green function for the Laplace-Beltrami operator on B, and let )~ denote the invariant measure on B. If # is a non-negative measure, or f is a non-negative measurable function on B, G~ and G s denote the Green potential of # and f respectively. For {e S = OB, r >~ 1, and c>0, let
~,~(~)={ze B:lt-r n. Then for each z, 1 <~l:
