Many- Electron Harmonium Atoms

Many-electron tunneling in atoms

A theoretical derivation is given for the formula describing N -electron ionization of atom by a dc field and laser radiation in tunneling regime. Numerical examples are presented for noble gases atoms. PACS numbers: 32.80.Fb, 87.64.Lg.

On The Electron Magnetic Moment Anomaly

It can be shown that the difference between the experimental value of the electron magnetic moment and that of the Bohr magneton is due to the magnetic drift of the electron's carrying energy induced at the hydrogen ground state gyroradius, corresponding to the electron being forced to move on a closed orbit about the nucleus in an isolated hydrogen atom.

A One-Dimensional Model for Many-Electron Atoms in Extremely Strong Magnetic Fields: Maximum Negative Ionization

We consider a one-dimensional model for many-electron atoms in strong magnetic fields in which the Coulomb potential and interactions are replaced by one-dimensional regularizations associated with the lowest Landau level. For this model we show that the maximum number of electrons Nmax satisfies a bound of the form Nmax < 2Z + 1 + c √ B where Z denotes the charge of the nucleus, B the field st...

Hartree-Fock-Roothaan calculations for many-electron atoms and ions in neutron-star magnetic fields

The quantitative analysis of the electromagnetic spectra of isolated neutron stars by means of model atmosphere calculations requires extensive data sets of atomic energy values and transition probabilities in intense magnetic fields. We present a new method for the fast computation of wave functions, energies, and oscillator strengths of medium-Z atoms and ions at neutron star magnetic field s...
