The plot of the ratio (C1f / C2f )D and (C1f / C2f )Lof discharge counts versus pulse height (bias-voltage) shows that this ratio for a constantpotential of 3.5 kV (rms) is initially large in value, then rapidly decreases to a minimum. It is alsoobserved that more is the surface-to-volume ratio, more is the magnitude of net effect of irradiation.Further, the pulse height analysis shows that the charge carried by the pulses to the electrodes(charge transfer) decreases under illumination. A possible mechanism to explain the net effectof the discharge current ratio in the light of pulse height measurements is discussed. ER -
