Abstract: Absolute excitation functions for excited fragments resulting from electron bombardment of H 2 0, NH3, and C.H4 by low. energy electrons (0-300 eV) have been measured in the VUV (1100-1950 A).The predommant emISSIOn for each molecule was the H Lyman-a line while the 01 NI CI and C II emissions were at least an order of magnitude weaker. Absolute cross sections ~t 1 00 ~V are given along with the appearance potential of the various processes and the possible dissociative-excitation channels through which such …
