The effect of anti-inhibition of radiolytic hydrogen formation in liquids

Attention is focused on that the phenomenon known as anti-inhibition in pos itronium chemistry is also observed in the radiolyses of liquids. In partic ular, the yield of radiolytic hydrogen from cyclohexane in the presence of molecular iodine increases when benzene is added to a cyclohexane solution. This effect is rationalized on the basis of the previously advanced idea o n the similarity between the formation mechanisms of positronium and radiol ytic hydrogen. The assumption that the enhancement of radiolytic hydrogen y ield in aqueous nitrate or nitrite solutions taking place upon addition of Mn2+, Co2+, Zn2+, etc. ions is also the manifestation of the anti-inhibitio n effect, which has been known neither for positronium nor for radiolytic h ydrogen in polar media, is substantiated.
