Relativistic Calculation of two-Electron one-Photon and Hypersatellite Transition Energies for Elements
M. C. Martins, A. M. Costa, J. P. Santos +2
Energies of two-electron one-photon transitions from initial double K-hole states were computed using the Dirac-Fock model. The transition energies of competing processes, the K$α…
Relativistic Calculation Of K Hypersatellite Energies and Transition Probabilities for Selected Atoms with 13<=Z<=80
A. M. Costa, M. C. Martins, J. P. Santos +2
Energies and transition probabilities of K hypersatellite lines are computed using the Dirac-Fock model for several values of throughout the periodic table. The influence o…
Resonant effects on the two-photon emission from hydrogenic ions
P. Amaro, J. P. Santos, F. Parente +2
A theoretical study the all two-photon transitions from initial bound states with ni = 2, 3 in hydrogenic ions is presented. High-precision values of relativistic decay rates for i…
Production and decay of Sulphur excited species in a ECRIS plasma
M. C. Martins, J. P. Marques, A. M. Costa +5
The most important processes for the creation of S12+ to S14+ ions excited states from the ground configurations of S9+ to S14+ ions in an electron cyclotron resonance ion source,…
X-ray energies of circular transitions and electrons screening in kaonic atoms
J. P. Santos, F. Parente, Paul Indelicato +2
The QED contribution to the energies of the circular (n,l=n-1), 2 ≤ n ≤ 19 transitions have been calculated for several kaonic atoms throughout the periodic table, usin…
Analysis of X-ray spectra emitted from laser-produced plasmas of uranium
J. P. Marques, Paul Indelicato, C. I. Szabo +1
In this paper, we used the multiconfiguration Dirac-Fock method to generate theoretical X-ray spectra for Co-, Ni-, Cu-, Zn-, Ga-, Ge-, As-, Se-, Br-, Kr-, and Rb-like uranium ions…
