Systematics of Electron, Proton and Photon Ionization Cross Sections

Abstract

Resumb.-Nous prksentons des rksultats concernant les calculations des sections, en utilisant un modkle mono-Hectronique noyau non relaxk, a h de calculer des forces d'oscillateur gknkraliskes. Nous avons trouvi: que les sections d'ionisation pour l'electron et le proton peuvent etre exprimks en une forme rkduite et possiblement universelle. Ensuite, nous discutons la possibilite d'exprimer les sections de photo-ionisation par une forme rkduite.

Absolute electron impactK-ionization cross sections of titanium and nickel (?50 keV)

“…The following Figs. 7 and 8 show the measured Kionization cross section in comparison with those of Pockman et al [10] and with data of different theoretical approaches (Rudge and Schwartz Fll], Gryzinski [12], Arthurs and Moiseiwitsch [13], Burhop [14], Mc Guire [15]). For impact energies above U = 1.5 a systematic deviation of about 20~o in comparison with calculations occurs as was observed earlier for aluminium by Hink and Ziegler [3] and for nitrogen, Oxygen and neon by Glupe and Mehlhorn [1].…”
