Abstract: The OI emissions (5577 Å and 6300 Å) are studied by using transport for proton precipitation. All possible sources of these emissions are considered. Recent experimental cross-sections and the reaction rate coefficients are used in the calculations The volume emission rates and the emission intensities of these emissions are calculated for Maxwellian distribution of precipitating protons and are compared with those obtained from the continuous slowing down approximation (CSDA). The yield of O(1D) due to the reaction of N(2D) with O2 is found almost negligible. The intensities of 5577 Å and 6300 Å emissions during the 4 Aug. 1972 polar cap absorption (PCA) event are also computed and a comparison is made with the measurements. The present calculated intensity ratio I (1577) / I(6300) is found in reasonable agreement with the measurements.
