The air between two closely located plates is uniformly ionized by ultraviolet radiation. The air volume between the plates is equal to V = 500 cm a, the observed saturation current is equal to I, = 0.48μA. Find: (a) The number of ion pairs produced in a unit volume per unit time; (b) The equilibrium concentration of ion pairs if the recombination coefficient for air ions is equal to r = 1.67 ∙ 10-6 cm3/s.
