The effect of photoinduced emission of alkali atoms from the paraffin coating of a cell on the spin relaxation time of the atoms was studied experimentally. No effect was detected. It was additionally found that long irradiation of the cell surface by light with a power density of about 1 mW/cm{sup 2} does not cause any degradation of the coating in spite of almost complete removal of the atoms from the coating due to their photostimulated diffusion in the layer and photodesorption. After the irradiation is complete, the surface contacting with the alkali vapor is again saturated with the alkali atoms with a time constant of about 1 h.
