Abstract
''Delayed'' photoionization of the all-carbon cage fullerene molecules C60 and C70 is observed using a weakly focused cw argon ion laser (fl ux I < 10(5) W/cm2). At these fluxes photoexcitation occurs incoherent ly and so slowly that intersystem crossing must be occurring simultane ously. A ''thermionic emission'' model adequately describes the delaye d ionization.
