Journal ArticleDOI
Multiple Ionization and Double Core-hole Production in Molecules using the LCLS X-ray FEL
Li Fang,Timur Osipov,Brendan Murphy,P. Juranic,Nora Berrah,Edwin Kukk,Kiyoshi Ueda,Raimund Feifel,P. van der Meulen,Peter Salén,Henning T. Schmidt,Richard D. Thomas,Mats Larsson,Robert Richter,Kevin C. Prince,John D. Bozek,Christoph Bostedt,Shin-ichi Wada,Maria Novella Piancastelli,Motomichi Tashiro,Masahiro Ehara,Francesco Tarantelli +21 more
TL;DR: In this article, the authors used the world's first hard x-ray FEL to investigate the response of molecular systems to the ultra-intense, femtosecond X-ray radiation.
Journal ArticleDOI
Photoionization study of doubly-excited helium at ultra-high resolution
TL;DR: In this article, the doubly excited states of He were studied at the 9.1 undulator beamline of the Advanced Light Source using a 925 lines/mm grating and entrance/exit slits as narrow as 2.5 μm with a total experimental width of 1.0.
Proceedings ArticleDOI
Double Core Hole Spectroscopy of Small Molecules
Kevin C. Prince,Robert Richter,Vitaliy Feyer,Nora Berrah,Li Fang,Brendan Murphy,Timur Osipov,Kiyoshi Ueda,Edwin Kukk,Raimund Feifel,Peter van der Meulen,Peter Salén,Henning T. Schmidt,Richard D. Thomas,Mats Larsson,John D. Bozek,Christoph Bostedt,Shin-ichi Wada,Maria Novella Piancastelli,Motomichi Tashiro,Masahiro Ehara +20 more
TL;DR: In this paper, the double ionization of small molecules and its application to obtain chemical information was discussed. But the double core holes were created by the sequential ionisation of matter.
Proceedings ArticleDOI

TL;DR: In this paper, an atomic inner-shell x-ray laser in neon at 1.46 nm wavelength was realized by photo-ionization pumping and stimulated resonant Raman scattering with an xray free-electron laser source.

TL;DR: In this paper, nonlinear absorption of femtosecond kilovolt x-rays in Neon is investigated and a possible two-photon ionization is observed with the presence of Ne9+ at photon energies below the Ne8+ 1s2 ionization threshold.
