EXPERIMENTAL STUDY OF SINGLE-ELECTRON-CAPTURE CROSS SECTIONS BY LOW-ENERGY $N^+_2$ AND N+ IONS IN N2 MOLECULAR GAS

Abstract

Absolute total cross sections for single-electron-capture are measured for [Formula: see text] and N+ ions traversing N2 molecular gas of collision energies in the range of 0.60 to 1.5 keV. These cross sections are found to be in the range of 3.97 - 6.25 Å2 for [Formula: see text] ions, and in the range of 0.46 - 1.67 Å2 for N+ ions. A comparison is made between the present measurements of the total cross sections of the N+ + N2 system and all the experimental results, which are represented by B. G. Lindsay et al.,1 for the O+ + N2 system. The present measurements of the total cross section of the N+ + N2 system are in partial agreement with measurements of B. G. Lindsay et al.,1 and in an excellent agreement with the measurements of Moran et al.,2 The present measurements of the total cross sections of the [Formula: see text] system are compared to the theoretical calculations and the experimental results of the same system.23 The results are in disagreement with each other.
