[[spi:math]] , (69) where the g-factor is [[spi:math]] . (70) In (70) the fabs is the oscillator strength for the Ly-[[spi:math]] radiation. In (69) [[spi:math]] is the column density of H-atoms. For the gravitationally trapped H-atoms belt, [[spi:math]]. (80) Thus, the Ly-[[spi:math]] intensification due to a single flight of the POTV would be ~ 600 Rayleighs. This must be compared with the geocoronal intensity at 200 km altitude of ~ 104 Rayleighs. 71 This estimate indicates that gravitationally trapped H-atoms from a single flight of the POTV is not of significant impact on the intensity of the geocorona. Further, unless the accumulation lifetime of the trapped H-atom belt is more than 10 flights of the POTV, intensification of the geocorona does not appear to be of much significance. It must be noted, however, that our result is based on the assumption that only burn 2 of the POTV burns will be gravitationally trapped while the rest of the chemical exhaust will escape the magnetosphere. This result emphasizes once again the importance of considering the accumulation lifetimes of the gravitationally trapped neutral belt.
