UDC 551.25:537.2

The photoemission charging of a collective of particles 
at normal atmospheric pressure and at lowered pressure of the air 
has been investigated. The dependences of the average initial charge 
of a droplet, the average equilibrium photoemission loss of charge 
by a droplet, and the equilibrium concentration of the electrons on 
the air pressure are presented as the basic experimental results. 
The process of photoemission charging of an aerodisperse system was 
theoretically described by solution of the equation of charge equilibrium 
of the average-radius particle with space charge. Comparison of the 
experimental and calculated results showed their satisfactory agreement.
