Abstract:

Experimental work is planned for 1 measurement of the photoionization cross section of krypton in the region 80 to 150 Angstroms and 2 examination, in both absorption and emission, of the elements adjoining xenon because of the large 4d shell photoionization cross section by the use of cesium and iodine compounds, comparison will be made of atomic theory with solid state absorption data. The photoionization cross sections of xenon and krypton are being calculated from the model wave functions of McGuire and Tomboulian Final states in photoionization. Cornell Univ., Ithaca, N. Y. Technical rept. 4 on Contract DA-31-124AROD-43, March 1964. By use of the same model, the atomic photoionization cross sections for elements near xenon in the periodic table can be calculated, thereby enabling separation of the atomic and solid state contributions to the cross section. Investigations are planned for extending the model to both higher and lower energies.
