  In present paper, by using the generalized DDC formalism, we investigate the
spontaneous excitation of an static atom interacting with electromagnetic
vacuum fluctuations outside a EGB black hole in $d$-dimensions. We find that
spontaneous excitation does not occur in Boulware vacuum. The Gauss-Bonnet term
has no effect on the stability of the atom. Finally, we discuss the
contribution of the coupling constant and dimensional factor to the results in
three different kinds of spacetime.
