We develop a method to compute the vacuum polarization energy for coupled
scalar fields with different masses scattering off a background potential in
one space dimension. As an example we consider the vacuum polarization energy
of a kink-like soliton built from two real scalar fields with different mass
parameters.Comment: 14 pages, 5 figures, matches journal version, references added
