    Evaporation rates of hot sodium clusters (1991)
    Springer
    The European physical journal 20 (1991), S. 119-122

    ISSN: 1434-6079
    Keywords: 36.40. + d ; 31.20.Sy ; 65.50. + m ; 63.70. + h

    Topics: Physics
    Notes: 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.

    Stability of isomeric Na n clusters (1991)
    Springer
    The European physical journal 19 (1991), S. 141-143 
    Details
    ISSN: 1434-6079
    Keywords: 31.20.Sy ; 36.40. +d
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A method which combines density functional theory and the use of pseudopotentials is applied to obtain ground state and low-lying metastable geometries of Na n clusters (7≤n≤40). The large variation in the magnitude of energy gaps between isomers suggests that the melting temperature is not a simple monotonous function of size. A detailed study of the differences between electronically stabilized (n=8, 20, 40) and structurally stabilized (n=13) clusters suggests some clues to understand the intriguing behaviour of Na13.
