Abstract
We have measured the side‐view intensity profiles of the N2+(1−) (0, 0) radiation emission caused by an electron beam fired into N2 gas. By Abel inversion the three‐dimensional radiation emission distribution has been computed from these profiles. Measurements were made for beam energies of 2.0–5.0 keV and gas density of 0.69–2.8 Torr. With proper normalization, the spatial intensity distribution shows no significant variation with voltage. The close relationship between the radiation, energy loss, and ionization deposition distributions is discussed. Integrals of our data reasonably agree with the theory of Spencer and Fano and the data of Grün.This publication has 14 references indexed in Scilit:
