On kinetic curves of photolysis speed PbN6(Аб) characteristic sites have been defined: initial, stationary, increased and saturation.

Preliminary light processing of PbN6(Аб) at λ=380 nm and I=2·1015 quantum·sm-2·s-1 in vacuum (Р=1·10-5 Pа) along with increase in photolysis speed and photocurrent in own area of absorption results in appearence of new long-wave area of spectral sensitivity. Quantum outputs and constants of photolysis speed of PbN6(Аб) are determined.
