SPECTROSCOPIC STUDY OF NITROGEN BOMBARDED BY HYDROGEN-IONS AT 1 MEV NUCLEON/

A nitrogen gas target at pressures from 5 to 200 mTorr (0.66 to 26.6 P a) was bombarded by ions of H+, H-2(+) and H-3(+) at energies of 1 MeV /nucleon. The collision region was studied spectroscopically in the uv and visible (1200 Angstrom to 5500 Angstrom) and shows the presence o f N I and N II lines, as well as several molecular bands of N-2 and N- 2(+). No emission of Lyman alpha at 1216 Angstrom was observed in the collision of 1 MeV H+ on nitrogen but the line was observed for the ca se of H-2(+) and H-3(+) projectiles. Scans in the visible showed that Balmer beta is very weak in all spectra, if at all present. Other qual itative features in the spectra were noted and considered in terms of various collision processes which can take place.
