Electron-impact excitation of krypton

Abstract

First-order many-body theory has been used to calculate the differential, integrated, and momentum-transfer cross sections for the electron-impact excitation of the 5s'${[(1/2)]}_{1}^{0}$(${}^{1}$${P}_{1}$ ), 5s${[(3/2)]}_{1}^{0}$(${}^{3}$${P}_{1}$), 5s'${[(1/2)]}_{0}^{0}$(${}^{3}$${P}_{0}$), and 5s${[(3/2)]}_{2}^{0}$(${}^{3}$${P}_{2}$) states of krypton for the incident energies of 20, 30, 50, 60, and 100 eV. Electron-photon coincidence parameters for the optically allowed states have been obtained. The results are compared to available experimental results.
