Stabilization method with Relativistic Configuration-interaction applied to two-electron resonances
P. Amaro, J. P. Santos, S. Bhattacharyya +2
We applied a relativistic configuration-interaction (CI) framework to the stabilization method as an approach for obtaining the autoionization resonance structure of heliumlike ion…
Experiments towards resolving the proton charge radius puzzle
A. Antognini, K. Schuhmann, F. D. Amaro +34
We review the status of the proton charge radius puzzle. Emphasis is given to the various experiments initiated to resolve the conflict between the muonic hydrogen results and the…
Quantized form factor shift in the presence of free electron laser radiation
F. Fratini, L. Safari, A. G. Hayrapetyan +3
In electron scattering, the target form factors contribute significantly to the diffraction pattern and carry information on the target electromagnetic charge distribution. Here we…
Analytical evaluation of atomic form factors: application to Rayleigh scattering
L. Safari, J. P. Santos, P. Amaro +2
Atomic form factors are widely used for the characterization of targets and specimens, from crystallography to biology. By using recent mathematical results, here we derive an anal…
Relativistic total cross section and angular distribution for Rayleigh scattering by atomic hydrogen
L. Safari, P. Amaro, S. Fritzche +2
We study the total cross section and angular distribution in Rayleigh scattering by hydrogen atom in the ground state, within the framework of Dirac relativistic equation and secon…
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,…
