Excitation of helium by electron impact

Journal of Applied Physics, 1981
A simple analytic central potential with two adjustable parameters is proposed for the helium atom. The potential parameters are obtained by appealing to the precise values of optical oscillator strengths calculated by Schiff et al. Using the Born approximation we calculate 1 1S–n 1P electron-impact excitation cross sections up to 5 keV. Good agreement

Electron impact excitation of bismuth

Physica Scripta
Abstract The present study investigates the electron impact excitation of bismuth from the ground state 6p3 4S3/2 to the excited state 6p27s 4P1/2. Motivated by the latest measurements by Marinković et al [J. Phys. B, 49 23 520 (2016)], relativistic distorted wave calculations are performed to obtain the differential ...

Threshold electron impact excitation

2011
Threshold electron impact spectra have been obtained for helium, neon, argon, krypton, xenon and carbon monoxide using a velocity-selected electron beam. Zero energy electrons ejected at excitation thresholds are scavenged by sulfur hexafluoride and the resulting SF(6)¯ ions are detected using a mass filter. Optically forbidden transitions are observed
