Abstract: rafast dynamics of solid C$-60$/ following optical excitation are discussed. Excitation into the lowest optical band using pulses 12 fs in duration centered at 620 nm results in coherent vibrational motion as well as nonexponential relaxation dynamics dominated by interactions between photoexcitations. Excitation at 500 nm into the next highest band reveals complex relaxation dynamics indicative of fast energy relaxation from the higher electronic state.!13
