| Abstract: | A scheme based in density functional theory with pseudopotentials is used to obtain the normal modes of vibration of Na n clusters (4 ≤n ≤ 22). The monomer and dimer evaporation rates from thermally excited clusters are obtained in this harmonic approximation. The time evolution of the abundance spectra from an initial uniform mass distribution of hot clusters is studied and its influence in the experimentally observed spectra is discussed. |
