摘要：

Paramagnetic radicals have been detected in solid CO2 with gamma irradiation at 77 K with the measurement of electron spin resonance (ESR). Species of O-3(-), CO3-, CH3, SO3- and HO2 are identified. The lifetimes of O-3(-), CH3 and HO2 at several temperatures were obtained by isothermal annealing experiments. Their stability at the ambient temperature of Mars and icy satellites was estimated from the Arrhenius plot of the lifetime for the future possibility of ESR dating of solid CO2.
