Abstract : The effect of light has been observed in the variation of discharge counts with pulse amplitude during d.c.. discharges through argon in a fresh and an aged Siemen's vessels. The pulse height spectra of the discharge for applied potentials of 1.75 and 1.82 kV (r.m.s.) have been measured in dark and under irradiation. The number of current pulses varies periodically with increasing amplitude both in the low and plateau-like intermediate amplitude regions; finally the number of pulse drops rapidly to negligible value in the high amplitude regions. The theoretical explanation for the various observed features in the plots has been attempted on the properties of adsorbed layers on the glass walls of the discharge tube.
