Experimental electron-impact K-shell ionization cross sections obtained fro
m a search of the literature up to December 1999 are tabulated according to
atomic number and incident electron energy. The data taken from the origin
al papers have been reevaluated, where necessary, using the K-shell fluores
cence yields compiled by Hubbell et al. and by Bambynek. Data are presented
for elements H through U. (C) 2000 Academic Press.
