Abstract
The gravitational scattering of various types of massless particles is considered. Cross sections are given for the gravitational scattering of scalar particles by: scalar particles, photons, four component neutrinos, and two component neutrinos; of photons by: photons, four component neutrinos, and two component neutrinos; of four component neutrinos by four component neutrinos; and of two component neutrinos by two component neutrinos. The cross section given by Barker et al. and by Boccaletti et al. for the scattering of photons by photons is confirmed. The cross section for the scattering of scalar particles by scalar particles given by DeWitt and the cross section for the scattering of photons by scalar particles given by Boccaletti et al. are found to be in error.Keywords
