Abstract: In this paper, we compute the scattering matrix for the Hilbert modular group over any number field $ K$. We then compute the determinant of the scattering matrix and show it is a ratio of completed Dedekind zeta functions associated to the Hilbert class field of $ K$. This generalizes work of Efrat and Sarnak in the imaginary quadratic case.
