Reexamination of collisional ionization cross sections including double photoionization processes
Lucas Ansia, Pedro Velarde, Marta Fajardo +1
Collisional ionization (CI) cross sections in dense plasmas remain difficult to constrain due to uncertainties in plasma conditions and the overlapping spectral signatures of compe…

Relaxation pathways in X-ray Free Electron Laser heated Iron
Lucas Ansia, Pedro Velarde, Marta Fajardo +1
Non-thermal photo-ionized plasmas are now established in the laboratory, and require models that treat the atomic processes and electron distribution self-consistently. We investig…

Shake-off in XFEL heated solid density plasma
G. O. Williams, L. Ansia, M. Makita +25
In atoms undergoing ionisation, an abrupt re-arrangement of free and bound electrons can lead to the ejection of another bound electron (shake-off). The spectroscopic signatures of…
