Kinetics of the radiative relaxation of the highly excited C60+* ion

The radiation of fullerene molecules from the intersection area of the C-60 beam with an electron beam with an energy of 27 less than or equal to E-e/eV less than or equal to 100 was studied experimentally under conditions of a single collision. It was found that ionized C-60(+.) molecules make the main contribution to the radiation. The radiation intensity and the temperature of C-60(+.) as functions of the energy E-e were measured. The kinetics of the radiation cooling of C-60(+.) was studied and the rate of the radiation loss of the ion energy (5.5 . 10(5) eV s(-1)) was determined at a temperature of 3150 K. For the heat model of radiation at the wavelength lambda = 540 nm, this corresponds to the emissivity epsilon = 1.1 . 10(-2).
