Multiple Scattering, the Glauber Approximation, and the Off-Shell Eikonal Approximation

Erratum: Refined Glauber model versus Faddeev calculations and experimental data for pd spin observables [Phys. Rev. C 81 , 014004 (2010)]

“…All these items were included later in the so-called relativistic multiple-scattering theory [5,6] which went beyond the Glauber framework by accounting for corrections to the eikonal and fixed-scatterer approximations and some relativistic effects as well. It is well known, at least qualitatively, that different corrections to the Glauber model tend to cancel each other substantially [7], so it is hard to improve the Glauber model essentially. Besides, the modified versions are much more complicated than the initial model.…”

“…[3][4][5][6]. However, the comprehensive analysis of various corrections to the Glauber model has revealed [7] that many important corrections to the initial model seems tend to compensate strongly each other, so that an incorporation of only one of them can even worsen the results of the initial simple model. So, it turned out to be highly nontrivial to improve the initial Glauber approach.…”

Monte Carlo eikonal scattering

“…16 (r) = 0.8646 v 1 (r) + 0.1354 v 2 (r)(51) with v 1 (r) = M 1 r 10 e −d16r ; v 2 (r) = M 2 (e −a16r − e −b16r ) 2 (52) anda 16 = 2.738 fm −1 ; b 16 = 0.2976 fm −1 ; d 16 = 4.174 fm −1 (53) FIG. 15: α− 16 O scattering at 240 MeV.…”

High-energy approximations to nuclear scattering

“…There has been considerable discussion, for potential scattering in the eikonal (Glauber) approximation [47][48][49][50][51][52], whether in addition the rescattering contributions Tr are negligible.…”
