| Abstract: | The escape rate of atmospheric molecules on the Moon is calculated. Based on the assumption that the rates of emission and
escape of gases attain equilibrium, the ratio of molecular number densities during day and night, n0d/n0n, can be explained. The plausible emission rate of helium and radioactive elements present in the Moon has also been calculated. |
