Abstract

In this paper we compute the low energy absorption cross section for minimally coupled massles scalars and spin- 1/2 particles into a general spherically symmetric black hole in arbitrary dimensions. The scalars have a cross section equal to the area of the black hole, while the spin- 1/2 particles give the area measured in a flat spatial metric conformally related to the true metric.
