    Group 12 Elements and Their Small Clusters: Electric Dipole Polarizability of Zn, Cd and Hg, Zn2 Dimer and Higher Znn< Microclusters and Neutral, Cationic and Anionic Zinc Oxide Molecules (zno, Zno+ and Zno-)
    (World Scientific Publ Co Pte Ltd, 2012) Oymak, Huseyin; Erkoc, Sakir
    This review is in general about group 12 elements and their small microclusters. In this part, after presenting an extensive literature survey of the electric dipole polarizability studies of the Zn, Cd and Hg atoms, we specifically target zinc-containing small clusters, beginning with the Zn-2 dimer, the Zn-3 trimer, higher Zn-n clusters and the neutral, cationic and anionic zinc oxide clusters: ZnO, ZnO+ and ZnO-. We tabulated experimental and theoretical results for the spectroscopic constants (dissociation energy D-e or D-0, bond length r(e), fundamental frequency w(e), anharmonicity constant w(e)x(e) and dipole moment mu(e)) of the diatomic clusters and the first and second ionization potentials IP1 and IP2 and electron affinity EA of the species reviewed.

    Minimum-Energy Distribution of Point Charges Confined To a Square
    (World Scientific Publ Co Pte Ltd, 2019) Oymak, Huseyin; Alkuwafi, Abdulwahhab
    The minimum-energy configurations of N(2 <= N <= 160) identical classical point charges confined within a square under the effect of a Coulombic 1/r potential have been determined by performing steepest-descent simulations. The energies of the final optimized configurations are given, along with their corresponding structural charge distributions. When all systems evolve in time to reach a minimum-energy configuration, local or global, they are all seen to be in quest of symmetry.
