The collisional excitation of nitrogen by low energy electrons to the second positive (C3∐u]) transition

Abstract

An experiment was conducted to determine the effective excitation cross sections for forming the C 3 n 2nd positive state of N ? in the lowest vibrational energy level by bombarding gaseous" nitrogen with electrons in the energy range 80 to 900 eV. When the nitrogen was bombarded by 250 eV electrons the effective cross section was determined to be (1.72 ± - 17 2 .22) x 10 cm , which was the maximum value of the cross section measured.
