Electronic Quantum Confinement in Cylindrical Potential Well
A. S. Baltenkov, A. Z. Msezane
The effects of quantum confinement on the momentum distribution of electrons confined within a cylindrical potential well have been analyzed. The motivation is to understand specif…
Doubly-charged Negative Ion of C60 Molecule
A. Z. Msezane, A. S. Baltenkov
Within the Dirac- and Lorentz-bubble potential models an electronic structure of the doubly-charged negative ion has been studied by a variational method. It is shown that even in…
Radiation Damping in the Photoionization of Fe^{14+}
M. F. Hasoglu, T. W. Gorczyca, M. A. Bautista +2
A theoretical investigation of photoabsorption and photoionization of Fe^{14+} extending beyond an earlier frame transformation R-matrix implementation is performed using a fully-c…
Regge resonances in low-energy electron elastic cross sections for Ge, Sn and Pb atoms: manifestations of stable excited anions
A. Z. Msezane, Z. Felfli, D. Sokolovski
Low-energy E < 2 eV electron elastic collisions with Ge, Sn and Pb atoms yield stable excited Ge-, Sn- and Pb- anions. The recent Regge-pole methodology is used with Thomas-Fermi t…
Photoionization of Ce - Ce
Zhifan Chen, Alfred Z. Msezane
Photoionization of the Ce - Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our r…
Novel Electron Spectroscopy of Tenuously and Weakly Bound Negative Ions
A. Z. Msezane, Z. Felfli, D. Sokolovski
A novel method is proposed that uses very slow electron elastic collisions with atoms to identify their presence through the observation of tenuously bound (electron impact energy,…
