Abstract
Kroh and Karolczak1 recently reported hydrogen yields in the γ-radiolysis of solid benzene–cyclohexane mixtures at −196° C which differed markedly from those observed in the liquid phase. The solid mixtures were prepared by plunging liquid samples into liquid nitrogen. Our results for such samples are shown by the open circles in Fig. 1, and are in qualitative agreement with those reported by Kroh and Karolczak. The samples were irradiated with cobalt-60 γ-rays at a dose rate of 2 × 1022 eV/l./h to doses of between 2 and 4 × 1022 eV/l.
