Elastic cross sections in an RSIIpscenario

The elastic differential cross section is calculated at low energies (below 100 MeV) for the elements 3 He, 20 Ne, 40 Ar, 14 N, 12 C, and for the 208 Pb using a finite electromagnetic potential, which is obtained by considering a Randall– Sundrum II scenario modified by the inclusion of p compact extra-dimensions. The length scale is adjusted in the potential to compare with known experimental data and to set bounds for the parameter of the model. The effective four-dimensional (4D) electromagnetic potential is produced by a point charge, as seen from the three-brane that contains it, in uniform motion in an RSIIp scenario.
