    Notes: Abstract The theory of shell correction developed for discussing fissing of heavy nuclei is applied to symmetric fragmentation of charged metal clusters. Assuming the effective potential of an anisotropic harmonic oscillator, we calculate the shell correction. We also calculate the energy of deformed charged droplets in the two-dimensional parameter space describing the deformation of droplets such as elongation and neck formation. The symmetric fragmentation of microclusters of alkali and noble metals is discussed.

    Shell effects on symmetric fragmentations of alkali-metal clusters (1991)
    Springer
    The European physical journal 19 (1991), S. 145-147 
    Details

    Notes: Abstract Symmetric fragmentation of multiply charged alkali-metal clusters consisting of several tens of atoms is studied. The energy variation during the fragmentation process is calculated using the theory ofshell corrections, in which total energy is written as a sum of the liquid-droplet and shell correction terms. It is found that the variation of the shell correction term is much larger than that of the liquid-droplet one if the parent cluster is metastable. Fragmentation into nearly-magic cluster is most favored regardless of parent size since the barrier height for fragmentation is mainly determined by the shell configuration of fragments rather than that of the parent.

    Phonon effect on enhancement and reduction of the superconducting transition temperature of a small particle and amorphous thin films (1993)
    Springer

    Notes: Abstract Using an elastic vibration model for phonons of an oxidized small metallic particle, size dependence of the superconducting transition temperature TC is derived. It is shown that the oxidization results in the reduction of TC with decrease in particle size. The main cause is that the surface oxide enhances the phonon frequencies as the particle size decreases. Superconducting character of amorphous thin films and its relation to an oxidized small particle is also discussed.
