THE PHOTOELECTRIC K-ABSORPTION CROSS SECTION OF BERYLLIUM

Abstract

Measurements of the absolute photoelectric absorption cross section for Be at photon energies slightly greater than the K-ionization threshold energy are presented. Photoelectric absorption by 2's in electrons is possible, but even if the data for wavelengths greater than 115A is extrapolated, the contribution to the total cross section appears to be negligible. This is in accord with the general expectation that K-absorption, if energetically possible, will be strongly favored over L-absorption. (Author)
