Abstract: In this paper the scattering problem for the prolate spheroid,

$\displaystyle \Delta {U_p} + {k^2}{U_p} = 0$

, is solved by way of an asymptotic parameter expansion, where the spheroid is considered a perturbation of a sphere (which has an exact solution). The error of the asymptotic approximation is then estimated.
