Measurement of differential collisional excitation cross sections for the K emission of He-like oxygen
Filipe Grilo, Chintan Shah, José Marques +3
We measure the energy-differential cross sections for collisional excitation of the soft X-ray electric-dipole K () emission from He-like oxygen (O VII), using an electro…
Experimental and theoretical approaches for determining the K-shell fluorescence yield of carbon
Philipp Hönicke, Rainer Unterumsberger, Mauro Guerra +8
The knowledge of atomic fundamental parameters, such as the fluorescence yields with low uncertainties, is of decisive importance in elemental quantification involving X-ray fluore…
Comprehensive Laboratory Measurements Resolving the LMM Dielectronic Recombination Satellite Lines in Ne-like Fe XVII Ions
Filipe Grilo, Chintan Shah, Steffen K"uhn +7
We investigated experimentally and theoretically dielectronic recombination (DR) populating doubly excited configurations (LMM) in Fe XVII, the strongest channel for soft X…
Revisiting the Fe XVII line emission problem: laboratory measurements of the 3s-2p and 3d-2p line-formation channels
Chintan Shah, José R. Crespo López-Urrutia, Ming Feng Gu +5
We determined relative X-ray photon emission cross sections in Fe XVII ions that were mono-energetically excited in an electron beam ion trap. Line formation for the 3s (3s-2p) and…
Roper Electroproduction Amplitudes in a Chiral Confinement Model
M. Fiolhais, P. Alberto, J. Marques +1
A description of the Roper using the chiral chromodielectric model is presented and the transverse and the scalar helicity amplitudes for the electromagnetic Nu…
N^* electroproduction amplitudes in a model with dynamical confinement
P. Alberto, M. Fiolhais, B. Golli +1
The Roper resonance is described in a chiral version of the chromodielectric model as a cluster of three quarks in radial-orbital configuration (1s)(2s), surrounded by …
