“…Characterization was done by thermo-analytical techniques, gel permeation chromatography, mechanical tests and via Rayleigh and Compton scattering. The results show that CAB with lower butyryl content can withstand higher operational temperatures and has greater mechanical strength while CAB with higher butyryl content seems to be more resistant to radiation.…”

“…Moreover, these back-converted photons originating from chameleons have an intrinsic difference with regenerated photons from axions: their relative polarisations are mutually orthogonal before Compton interacting with the surrounding plasma. Depending on the photon-chameleon coupling and working in the strong coupling regime of the chameleons to matter, we find that the induced photon flux, when regenerated resonantly with the surrounding plasma, coincides with the solar flux within the soft X-ray energy range. …”

“…Il volume si propone lo scopo di fornire al lettore i concetti fisici fondamentali che stanno alla base della spettroscopia atomica e dei processi di emissione e assorbimento della radiazione nei plasmi di laboratorio e astrofisici, coprendo argomenti fondamentali quali gli spettri atomici di atomi a uno o più elettroni, la quantizzazione del campo elettromagnetico, l'interazione fra materia e radiazione (trattata sia dal punto di vista classico che quantistico), le transizioni radiative, i fenomeni di equilibrio e non-equilibrio nei plasmi, la teoria del trasporto radiativo, l'emissione della radiazione di ciclotrone, di sincrotrone e di frenamento, e la diffusione Compton relativistica (trattata col formalismo della seconda quantizzazione). …”

“…Range cuts for electromagnetic processes exploit a built-in feature of Geant4 and terminate low energy electrons that originate from physics processes including conversions, the photoelectric effect, and Compton scattering. Both algorithms were tuned to maintain physics performance in ATLAS and together they bring about a 20% speedup of the ATLAS Geant4 simulation. …”
