Abstract

In the paper there are presented results of study of the Hercshel effect (HE) for a number of s I lver hal ide ho 1 ographic photomateri al s such as BPI1 J1014-2Y. 11014-3 14A3 under exposure by act iri c and nonact I ni c 1 aser radi at Ion (NAR) of various durations (10 10 10 s). The observed in experiment reciprocity law failure according to the HE is specified by different contributions of electron and hole components of the HE. In accordance with such a not ion the centers of 1 atent I mage C LI ) can be damaged by two ways : 1) absorption of NAR by LI center accompanied by transition of electron into conduction band with the following recombination and 2) release under the action of NAR of holes from surface traps into valence band and their recombination with electrons trapped in the LI centeis. It is shown that Intensification of the HE under the action of NAR of 10 s duration depends in the main on the hole component. Results obtained in studies of the HE for photomaterials with different types of chemical and spectral sensitization as well as after their treatment with chemical reagents specifying the kinetics of free charge carriers on surface of emulsion microcrystals permit to refine the notion about their part in processes of LI formation. 1.
