Measuring cesium electron impact cross-sections using a magneto-optical trap

MacAskill, J.A., Kedzierski, W., McConkey, J.W., Domyslawska, J. and Bray, I. (2002) Measuring cesium electron impact cross-sections using a magneto-optical trap. Journal of Electron Spectroscopy and Related Phenomena, 123 (2-3). pp. 173-184.

Experimental and theoretical results for electron impact total cross-sections in Cs are presented over the energy range 0.3-400 eV. Good agreement is obtained between Convergent Close Coupling calculations and experimental measurements carried out using a magneto optical trap. A long standing question regarding the energy variation of the total cross-section for ground state targets is resolved. For energies above 10 eV, total cross-sections involving the excited 6 2P state are about 1.5 times those for the ground state at the same energy.
