| Alkali atoms are highly polarizable targets for electron scattering and this interaction must be taken into account. We know that the polarization potential is the representation of the distortion of the target alkali atom by incident electrons. In order to calculate this polarization potential, the adiabatic non-perturbative relativistic polarized orbital (RPO) method, within the framework of the Dirac equations, using j-j coupled wave functions has been used in this work. Recently this RPO method was generalized by McEachran et al. (2004) for use with heavy alkali atoms and successfully used to calculate dipole polarization potentials of cesium. We have used this RPO method to calculate dipole polarization potentials of cesium and rubidium. Then these polarization potentials have been used to calculate differential cross sections, exchange asymmetry (Aex), spin-orbit asymmetry (Aso) and interference asymmetry (Aint) parameters. We have used a different numerical calculation in this work. Finally these results have been compared with experimental and other theoretical results. |
