"Total Electron Impact Ionization Cross Section In Rubidium From Thresh" by Kaare J. Nygaard and Yu Bong Hahn
 

Abstract

A study of ionization in rubidium has been made in a crossed atom-electron beam apparatus. At an electron energy of about 10 eV there is a maximum in the cross section corresponding to the maximum probability for removal of the 5s valence electron. At 16.5 eV we have observed a new peak that is caused by the mechanism of autoionization. For energies below 30 eV there is a good agreement, both in shape and magnitude, between the present measurements and the empirical formula of Lotz. The over-all uncertainty in the measurements is ± 12% which is mostly accounted for by the uncertainty in the determination of the rubidium number density. 1 Present address: Department of Physics, University of Windsor, Windsor, Ont., Canada.
