Abstract
The production of the oxygen 5577 Å emission in purified nitrogen at atmospheric pressure by radiation with Po-210 alpha was studied spectroscopically. When the concentration of oxygen in the nitrogen was one part in ten thousand, the most intense emission observed was that of the forbidden atomic oxygen (1S → 1D) transition. This line emission at 5577 Å was seen to be associated with a continuum that extended from approximately 5600 to 5400 Å. To determine the reaction mechanism producing this emission, the effects of an electric field, temperature, and concentration of oxygen were examined. Several possible mechanisms are considered. The reaction producing oxygen atoms excited to the 1S state which we found most favorable is shown below. N++O2→NO++O(1S).Keywords
