We experimentally obtained a direct image of the nuclear wave functions of H(2)(+) by dissociating the molecule via electron attachment and determining the vibrational state using the cold target recoil ion momentum spectroscopy technique. Our experiment visualizes the nodal structure of different vibrational states. We compare our results to the widely used reflection approximation and to quantum simulations and discuss the limits of position measurements in molecules imposed by the…

Multiphoton above threshold effects in strong-field fragmentation.
TLDR
For the first time-how multiphoton structure prevails as long as one accounts for the energies of all the fragments is shown, which provides a new avenue to analyze strong-field fragmentation that leads to a deeper understanding of the correlated molecular dynamics.
Imaging of spatial many-body wave functions via linear momentum measurements.
TLDR
It is concluded that prudent imaging of many-body fragmentation provides a laboratory view of the squared many- body wave function at a spatial scale of molecular dimensions at which fragments exit into the realm of independent free particles.
Theory of dissociative tunneling ionization
We present a theoretical study of the dissociative tunneling ionization process. Analytic expressions for the nuclear kinetic energy distribution of the ionization rates are derived. A particularly
Imaging the square of the correlated two-electron wave function of a hydrogen molecule
TLDR
The authors demonstrate the imaging of the correlated two-electron wave function in hydrogen molecule using the coincident detection of the electron and proton after the photoionization.
Reaction imaging in uniform electric and magnetic fields
We extend our recent analysis (Briggs and Feagin 2013 J. Phys. B: At. Mol. Opt. Phys. 46 025202) of the imaging theorem relating the asymptotic coordinate and momentum wavefunctions describing a
Site-selective photoemission from delocalized valence shells induced by molecular rotation.
TLDR
It is shown that the use of high-energy photons to photoionize valence-shell electrons of hydrogen chloride offers an unexpected way to decrypt the atomic composition of the molecular orbitals due to the rotational dependence of the photoionization profiles.
H2: the benchmark molecule for ultrafast science and technologies
This review article focuses on imaging and controlling ultrafast dynamics of the hydrogen molecule and its cation, initiated by ultrashort laser pulses. We discuss the mechanisms underlying these
