Electron Impact Ionization of H$_2$
POSTER
Abstract
Relative doubly-differential cross sections for the low energy electron impact ionization of H$_2$ have been measured. Measurements have been completed at 30~eV incident energy and scattering angles of $60^\circ$ and $90^\circ$, and at 40~eV incident energy and scattering angles of $50^\circ$ and $90^\circ$. The calibration of the electron analyzer during these measurements employed the recent doubly-differential cross section measurements of atomic hydrogen.\footnote{J.\ G.\ Childers, K.E.James, Jr., Igor Bray, M.\ Baertschy, and M.\ A.\ Khakoo, {\em Phys.Rev.\ A} {\bf 69}, 022709 (2004).} These measurements represent a new calibration standard useful in the determination of the transmission function of electron analyzers. This work is funded by the National Science Foundation under grant \# NSF-RUI-PHY-0096808.
