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

An oxygen gas target at pressures from 5 to 200 mTorr (0.66 to 26.6 Pa ) was bombarded by H+, H-2(+) and H-3(+) ions at an energy of 1 MeV/nu cleon. The collision region was studied spectroscopically in the UV an d visible (400 Angstrom to 6500 Angstrom) and shows the presence of O I, O II and O III lines, as well as several molecular bands of O-2 and O-2(+). The O I and O II levels were populated up to levels 3 and 4. The pressure dependence of the intensities of various lines was also m easured for proton projectiles.
