Measurement of absolute differential cross sections for the vibrational excitation of molecular nitrogen by electron impact in the {sup 2}{Pi}{sub g} shape resonance region
- Univ. of Michigan, Ann Arbor, MI (United States)
Using a crossed-beam technique, the authors have measured absolute differential cross sections for the vibrational excitation of N{sub 2} by electron impact. The scattering angle range of 12 through 156{degrees} was treated, in 12{degrees} increments. The impact energies 1.9, 2.1, 2.4, and 2.6 eV were used, where both the elastic and vibrational-excitation scattering cross sections of N{sup 2} suffer their maximum resonant enhancements. Strong D-wave character was present in all the absolute differential cross sections. Integrated cross sections were computed from the differential cross sections. Their results are compared with both the recent experimental and the recent theoretical results of others.
