DESCRIPTION:Speakers: Santosh Bhatt (University of Tennessee at Knoxville)
\nThe analytical abrasion-ablation model has been used for the quantitativ
e predictions of the neutron and light ion spectra from nucleus-nucleus an
d nucleon-nucleus collisions. The abrasion stage of the current model is b
ased on the Glauber's multiple scattering theory and applies the small ang
le approximation which assumes the longitudinal momentum transfer for the
scattering amplitude to be small\, where the expansion of the scattering a
mplitude is only considers first order terms. However the validity of the
small angle approximations for the current model is not clear for light io
ns and nucleons. In this work\, we have re-derived the phase functions\, c
hi\, for the calculation of nuclear cross-sections using a perturbation ap
proach and expanded Fourier-Bessel arguments of scattering amplitude in te
rms of Legendre polynomials\, thus eliminating the small angle approximati
on. We have computed the differential cross-section for various projectile
-target data sets at different energies for different scattering angles an
d compared our results with the usual Glauber model.\n\nhttps://indico.phy
