Photon-momentum-induced molecular dynamics in photoionization of N $_{2}$ at $h ν = 40$ keV

M. Kircher, J. Rist, F. Trinter +16

We investigate K-shell ionization of N $_{2}$ at 40 keV photon energy. Using a COLTRIMS reaction microscope we determine the vector momenta of the photoelectron, the Auger electron an…

Recoil-Induced Asymmetry of Nondipole Molecular Frame Photoelectron Angular Distributions in the Hard X-ray Regime

M. Kircher, J. Rist, F. Trinter +15

We investigate angular emission distributions of the 1s-photoelectrons of N $_{2}$ ionized by linearly polarized synchrotron radiation at $h ν = 40$ keV. As expected, nondipole contribu…

Separating Dipole and Quadrupole Contributions to Single-Photon Double Ionization

S. Grundmann, F. Trinter, A. W. Bray +12

We report on a kinematically complete measurement of double ionization of helium by a single 1100 eV circularly polarized photon. By exploiting dipole selection rules in the two-el…
