Abstract

We observed a continuous emission spectrum of 60 * and C 60 +* clusters induced by electron impact for wavelengths 300 to 800 nm (the monochromator’s resolution was Δλ = 3.2 rim). The emission spectrum was described by a modified Planck’s formula for the black-body-like radiation. The radiative temperature of clusters, T,(up to 3100 K) and the integral intensity of emission depend on the electron energy E e in a beam. The intensity of emission from C 60 + is higher than that from a neutral cluster. The emissivity coefficient has been found to be ε(C 60 +* ) = 7.6 × 10−3.
