Abstract

Relaxation dynamics of the optically excited state in Al-n with n=6 15 were studied using time-resolved two photon photoemission spectroscopy. Relaxation rates of these Al clusters are slower than those of some d-metal clusters which can be explained by lower electron density of state in the sp-metals. The relaxation rate of Al−13, a magic cluster anion with a closed electronic shell is as fast as the non-magic clusters such as Al−10, implying that the relaxation dynamics of magic clusters cannot be rationalized by the electron electron scattering. Origin of this unexpected behaviour of the magic cluster is discussed.
