LCLS in - photon out: fluorescence measurement of neon using soft x-rays
Razib Obaid, Christian Buth, Georgi L. Dakovski +10
We measured the fluorescence photon yield of neon upon soft x-ray ionization (~1200 eV) from the x-ray free electron laser at Linac Coherent Light Source, and demonstrated the usag…
Dissociating diatomic molecules in ultrafast and intense light
Christian Buth
An theory is devised for the quantum dynamics of molecules undergoing (multiple) ionization in ultrafast and intense light. Specifically, the intertwined prob…
Neon in ultrashort and intense x rays from free electron lasers
Christian Buth, Randolf Beerwerth, Razib Obaid +3
We theoretically examine neon atoms in ultrashort and intense x rays from free electron lasers and compare our results with data from experiments conducted at the Linac Coherent Li…
Nonlinearity in the sequential absorption of multiple photons
Christian Buth
I classify multiphoton absorption into separable, linked, and simultaneous processes. The first and second types can be distinguished when the rate-equation approximation is valid…
Rate equations for nitrogen molecules in ultrashort and intense x-ray pulses
Ji-Cai Liu, Nora Berrah, Lorenz S. Cederbaum +4
We study theoretically the quantum dynamics of nitrogen molecules (N) exposed to intense and ultrafast x-rays at a wavelength of 1.1 nm (1100 eV photon energy) from the Linac C…
Broadband high-resolution x-ray frequency combs
Stefano M. Cavaletto, Zoltan Harman, Christian Ott +3
Optical frequency combs have had a remarkable impact on precision spectroscopy. Enabling this technology in the x-ray domain is expected to result in wide-ranging applications, suc…
