Gn. Ogurtsov, DIFFERENTIAL CROSS-SECTIONS FOR IONIZATION OF ATMOSPHERIC GASES BY ELECTRON-IMPACT, Journal of physics. B, Atomic molecular and optical physics, 31(8), 1998, pp. 1805-1812
Absolute values of doubly differential cross sections for electron eje
ction in collisions of fast electrons with H-2, N-2, CO and CO2 molecu
les have been measured at the electron ejection angle of 54.5 degrees,
in the incident electron energy range 100-1000 eV and in the ejected
electron energy range 5-50 eV. Singly differential cross sections are
also determined using a normalization procedure. The measured cross se
ctions agree well with available data of other authors, except for tho
se on e(-)-H-2 at 1000 eV, where a disagreement of up to a factor of 3
is observed. However, a rather good agreement is found between experi
mental data of this work at high energies and calculations using the B
orn approximation.
