QUASI-CLASSICAL EFFECTIVE HAMILTONIAN-STRUCTURE OF ATOMS WITH Z=1 TO Z=38

The Kirschbaum-Wilets quasiclassical, many-body atomic model [Phys. Rev. A 21, 834 (1980)] is applied to atoms and ions having 1Z38. An efficient method was found to search for the global minimum of the energy functional. A quasiclassical shell structure is shown to result from the Hamiltonian formulation in terms of momentum-dependent potentials representing quantum-mechanical effects codified in the Heisenberg and Pauli principles. Along with ionization and correlation energies, the ground-state configurations are presented for use as initial conditions in various dynamical calculations. © 1995 The American Physical Society.
