Electron impact ionization cross section of metastable N2(A Σ+/sub u/)

Description

The nondissociative electron impact ionization cross section of the metastable N2(A 3Σ+/sub u/) state is measured from threshold to 240 eV. Rising from an appearance potential of 10.1 +- 0.6 eV, the cross section peaks at about 40 eV with a value of (1.14 +- 0.36) x 10-16 cm2. These values are extracted from the apparent ionization cross section of an N2 beam composed of approx.50% N2(A 3Σ+/sub u/) and approx.50% N2(X 1Σ+/sub g/). This mixed state beam is formed by charge transfer neutralization of a 1 keV N+2 beam with NO. The N2(A 3Σ+/sub u/) cross section is normalized by measuring it relative to the ionization of a ground state N2 beam formed by charge transfer neutralization of N+2 with N2
