Delayed'' photoionization of the all-carbon cage fullerene molecules C[sub 60] and C[sub 70] is observed using a weakly focused cw argon ion laser (flux [ital I][lt]10[sup 5] W/cm[sup 2]). At these fluxes photoexcitation occurs incoherently and so slowly that intersystem crossing must be occurring simultaneously. A thermionic emission'' model adequately describes the delayed ionization.
