Scientific paper

The recombination of O2(+) represents a source of fast oxygen atoms in Venus' exosphere, and subsequent collisions of oxygen atoms with hydrogen atoms lead to the escape of about 10 to the 7th hydrogen atoms/sq cm per sec. Escape of deuterium atoms is negligible, and the ratio of deuterium to hydrogen should increase with time. It is suggested that the mass-2 ion observed by Pioneer Venus is D(+), which implies a ratio of deuterium to hydrogen in the contemporary atmosphere of about 0.01, an initial ratio of 0.00005, and an original H2O abundance not less than 800 g/sq cm.
