The relativistic R-matrix method is used to calculate elastic and inelastic cross sections for electrons incident on caesium atoms with energies from 0-3 eV. In addition to the total cross sections, results are presented on the differential cross section, cr, and the spin polarisation, Py, of the scattered electrons as a function of energy at the scattering angles IO", SO", 90" and 150". The calculation reveals a wealth of resonances around the 2P,,, and 2P,,, thresholds. The resonances are analysed in detail and their role in the scattering process is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
