Two-color X-ray pulses with controlled time delay allow exciting one site of a molecule and then probing a different site of the same molecule with femtosecond resolution. Here, the authors use this hetero-site pump-probe technique to study charge re

We present a joint experimental and theoretical study of the gerade and ungerade amplitudes of the photo double ionization of helium at excess energies of 100 eV and 450 eV above the threshold. We describe a method of extracting the amplitudes from a

We have measured absolute triple differential cross sections for photo-double ionization of helium at 20 eV excess. The measurement covers the full ranges of energy sharing and emission angles of the two photoelectrons. We compare our data for select

Recoil ion momentum spectroscopy has been used to map the entire five-dimensional momentum space of the photo double ionization of helium at 20 eV above threshold. Angular asymmetry parameters for the relative motion of the electrons and the recoil i

The study of energy- and angle-resolved double photoionization leads to the triple-differential cross section (TDCS) which can provide, except for the spin polarization of the electrons, the most complete information on the double photoionization pro

Measurements of the neon 2p4 1Se triple differential cross section of photoionization have been performed under experimental setups differing in such conditions as the electron kinetic energies (equal energy sharing), the plane in which the electrons

The triple differential cross section for double photoionization in helium has been measured for the first time. Equal energy sharing and a simple geometry for the two emitted electrons were chosen in order to facilitate the comparison with theory. G

We report, to our knowledge, the first dressed absorption spectrum at an X-ray probe wavelength. An ultrafast optical pulse induces transparency for X-rays, demonstrating a promising route to femtosecond X-ray pulse shaping and measurement.

In x-ray science, cross-sections for x-ray absorption in matter are typically assumed to be invariants, depending only on the atomic and spatial composition of the material. However, by utilizing strong electromagnetic fields, it is possible to modif
