A semiclassical analysis is proposed to elucidate quantitatively the deviations from the predictions of the random matrix theory of the observed conditional number density in rectangular billiards with point scatterers [R. L. Weaver and D. Sornette, Phys. Rev. E 52, 3341 (1995)]. Using the scattering cross section of the point scatterer, the spectral form factor is shown to be built on two categories of periodic orbits depending whether they are scattered or not. Our quantitative predictions are successfully compared to the observed spectral correlations in various cases of a rectangular billiard with one or several point scatterers.
