Stationary components of HeI in strong magnetic fields - a tool to identify magnetic DB white dwarfs
S. Jordan, P. Schmelcher, W. Becken
In only three of the 61 known magnetic white dwarfs helium has been identified unambiguously while about 20% of all non-magnetic stars of this class are known to contain HeI or HeI…
Nonzero angular momentum states of the helium atom in a strong magnetic field
Wolfgang Becken, Peter Schmelcher
The electronic structure of the helium atom in the magnetic field regime B=0-100a.u. is investigated, using a full configuration interaction approach which is based on a nonlinearl…
Exchange and correlation energies of ground states of atoms and molecules in strong magnetic fields
P. Schmelcher, M. V. Ivanov, W. Becken
Using a Hartree-Fock mesh method and a configuration interaction approach based on a generalized Gaussian basis set we investigate the behaviour of the exchange and correlation ene…
The helium atom in a strong magnetic field
W. Becken, P. Schmelcher, F. K. Diakonos
We investigate the electronic structure of the helium atom in a magnetic field b etween B=0 and B=100a.u. The atom is treated as a nonrelativistic system with two interactin g elec…
