摘要：

In [1] we studied the absorption cross section of a scalar field of mass m impinging on a static black hole of mass M and charge Q. We presented numerical results using the partial-wave method, and analytical results in the high-and low-frequency limit. Our low-frequency approximation was only valid if the (dimensionless) field velocity v exceeds v(c) = 2 pi Mm. In this addendum we give the complementary result for v less than or similar to v(c), and we consider the possible physical relevance of this regime.
