Abstract
We calculate the absorption cross section of a massive neutral scalar field impinging upon a Reissner-Nordström black hole. First, we derive key approximations in the high- and low-frequency regimes. Next, we develop a numerical method to compute the cross section at intermediate frequencies, and present a selection of results. Finally, we draw together our complementary approaches to give a quantitative full-spectrum description of absorption.

In Ref. [11] it is shown that the low-frequency limit of the transmission coefficient for small black holes behaves as , so that the contribution is dominant in this limit.
