As an application O(\alpha_s^2) corrections to + the decay of a scalar and pseudo-scalar Higgs boson into top quarks + are considered. It is shown that for a Higgs mass not far above the + $t\bar{t}$ threshold these higher order mass corrections are necessary + to get reliable results. + + + |**R. Harlander and M.
