||P.131 right column top paragraph: "As shown in Table 1, there are no more undissociated oxygen molecules present above 1000 km height where the exosphere starts. At 2000 km height the exosphere contains only 0, He and H atoms. The fact that 0 and H are present and not N, should indicate a source for both H
and 0 atoms. The ratio 0/H is 1:1, which indicates that when the H+ (or proton) is formed from dissociated H2O, there should be at least twice the amount of H over O. Since the ratio is 10^3 0 ions/cm^3: 10^3 H ions/cm^3 (Tab. 1) and given the uncertainty of the data, one may tentatively conclude only that part of the hydrogen (protons) has escaped to space."
