Study of the Penning ionization processes in the N{sub 2}-He system by plasma electron spectroscopy

Journal Article · · Optics and Spectroscopy
OSTI ID:105423
Electron spectra of the Penning reactions for nitrogen molecules ionized by metastable helium atoms are detected by plasma electron spectroscopy. The ratio of the Penning ionization rate constants, 2.1{+-}0.4, is obtained for singlet and triplet metastable helium states. This made it possible to obtain the rate constant (15{+-}3) {times} 10{sup {minus}11} cm{sup 3}/sec for the Penning ionization of nitrogen molecules by singlet-state metastable helium atoms. 13 refs., 1 fig.
