Abstract

On the basis of our recent review of experimental cross sections for K-shell ionization by light ions, we present a table of best-fitted cross sections for protons on all elements from 4Be to 92U. Experimental cross sections are first normalized by the ECPSSR theory of Brandt and Lapicki; then the normalized values are averaged, interpolated, and used to produce reference cross sections (19 values per energy decade). Particular attention is given to assigning a reasonable uncertainty to the reference values: the error consists of a calculated random contribution and an estimated systematic contribution which describes both the influence of a small deficiency of the theory and the influence of possible bias in the data. A complete list of experimental data is given.
