An improvement of the Moliere-Fano multiple scattering theory    [PDF]

Alexander Tarasov, Olga Voskresenskaya
In the framework of unitary Glauber approximation for particle-atom scattering, we have received an improvement of the Moliere-Fano theory (M-F theory) on the basis of reconstruction of the generalized optical theorem in it. We have estimated the relative unitary and the Coulomb corrections to the parameters of the M-F theory and studied the Z-dependence of these corrections. We showed that the absolute and relative inaccuracies of the Moliere's theory in determining the screening angle for heavy atoms of the target material (Z~80) are about 20% and 30%, respectively.
