New method to determine the physical parameters of the gas in neutral atmospheres of comets is proposed in the paper. Application of circular diaphragms method to photometric observations of comet 2009/P1 (Garradd) showed that this method is suitable for determination of the hydrodynamic velocity of gas outflow and the lifetime of the molecules in the neutral atmospheres of comets.
