Guinea, W. E. and Hanne, G. F. and Went, M. R. and Daniell, M. L. and Stevenson, M. A. and Bartschat, K. and Payne, D. and MacGillivray, W. R. and Lohmann, B. (2005) Spin asymmetries in elastic and inelastic scattering from rubidium. Journal of Physics B: Atomic, Molecular and Optical Physics, 38 (18). pp. 3359-3366. ISSN 0953-4075


Experimental and theoretical results are presented for the A2 spin asymmetry for elastic and inelastic scattering of spin-polarized electrons from rubidium, at incident electron energies of 15, 20, 30, 50 and 80 eV. Theoretical calculations are performed within a semi-relativistic Breit-Pauli R-matrix (close-coupling) model. The experimental data reveal significant asymmetries at all energies. The experimental results are reasonably well described by the present theoretical calculations and by other calculations using a relativistic distorted-wave approach, and provide a clear relativistic signature.
