Radiation induced defects in naphthalene and anthracene single crystals irradiated with reactor neutron at 10°∼17°K were studied by ESR at 4.2°K, 77°K, and room temperature. Initial radicals produced in naphthalene at low temperature have been identified to be α-naphthyl radical and isolated hydrogen atoms, whereas in anthracene 9-anthryl radical and isolated hydrogen atoms have been detected. At room temperature the ESR signals of these radicals disappear, and α-hydronaphthyl radicals and dibenzo-cyclohexadienyl radicals have been detected innaphthalene and anthrance, respectively. The results indicate the following processes in the radiation damage in naphthalene and anthracene: RH+Reactor Neutron &roar;R+H, RH+H &roar;Rh_2.
