Abstract Studies were made on the gamma and ultraviolet radioinduced excitation of a deoxygenated 10/sup -2/ M solution of naphth in MP (isopentane- methylcyclohexane) at 77 deg K. Both fluorescence and phosphorescence were observed during Utraviolet irradiation, gamma irradiation, and thermoluminescence experiments, but it was found that relative to ultraviolet excitation, phosphorescence was enhanced by gamma excitation and the enhancement was still greater in thermoluminescence. Approximate calculations of the excitation were made. The thermoluminescence was ascribed to naphthalene ion recombination. (P.C.H.)
