Angular correlations in the two--photon decay of helium--like heavy ions
A. Surzhykov, A. Volotka, F. Fratini +5
The two-photon decay of heavy, helium-like ions is investigated based on second-order perturbation theory and Dirac's relativistic equation. Special attention has been paid to the…
New expression for the K-shell ionization
J. P. Santos, M. Guerra, F. Parente
A new expression for the total K-shell ionization cross section by electron impact based on the relativistic extension of the binary encounter Bethe (RBEB) model, valid from ioniza…
K X-Ray Energies and Transition Probabilities for He-, Li- and Be-like Praseodymium ions
J. P. Santos, A. M. Costa, M. C. Martins +2
Theoretical transition energies and probabilities for He-, Li- and Be-like Praseodymium ions are calculated in the framework of the multi-configuration Dirac-Fock method (MCDF), in…
Relativistic transition wavelenghts and probabilities for spectral lines of Ne II
J. P. Santos, A. M. Costa, C. Madruga +2
Transition wavelengths and probabilities for several 2p4 3p - 2p4 3s and 2p4 3d - 2p4 3p lines in fuorine-like neon ion (NeII) have been calculated within the multiconfiguration Di…
