title: Isothermal annealing kinetics of X-irradiated pyrene by electron paramagnetic resonance.
abstract: The annealing behavior of X-irradiated stable free radicals found in pyrene (C16H10) single crystals was studied by electron paramagnetic resonance. Two processes of thermal decay kinetics were found, both with the same activation energy: 1.9 +/- 0.1 eV.
