Photoelectric Responses of Stainless Steel to Monochromatic Light

Photoelectric responses of unpretreated 1Cr18Ni9Ti stainless steel immersed insolution are quite weak aud difficult to detect. Photoresponses of such stainless steelto polychromatic light over the visible range of radiation have been detected quanti-tatively, for the first time, by the present authors using signal averaging techni-que. More information may be acquired with monochromatic light excitation. How-ever, photoresponses to monochromatic light are decreased by a factor of 300 com-
