A new method to compute the incoherent scattering function of harmoniclattices is introduced. It is based in a saddle point approximation for eachterm of the phonon expansion, and is simple enough to be used in practice. Themethod gives very accurate results even for the tails of the scatteringfunction, and is more accurate than the usual gaussian approximation, which canbe derived from this saddle point approximation in the limit in which the orderof the phonon expansion term becomes large. Numerical comparisons are providedusing vanadium as a test case.
