Pu Electronic Structure and Photoelectron Spectroscopy

Probing the electronic and vibrational structure of Au2Al2(-) and Au2Al2 using photoelectron spectroscopy and high resolution photoelectron imaging.

The electronic and vibrational structures of Au2Al2(-) and Au2Al2 have been investigated using photoelectron spectroscopy (PES), high-resolution photoelectron imaging, and theoretical calculations. Photoelectron spectra taken at high photon energies with a magnetic-bottle apparatus reveal numerous detachment transitions and a large energy gap for the neutral Au2Al2. Vibrationally resolved PE sp...

EXPERIMENTAL BENCHMARKING OF Pu ELECTRONIC STRUCTURE

The objective of this work is to develop and/or apply advanced diagnostics to the understanding of aging of Pu. Advanced characterization techniques such as photoelectron and x-ray absorption spectroscopy will provide fundamental data on the electronic structure of Pu phases. These data are crucial for the validation of the electronic structure methods. The fundamental goal of this project is t...

A joint photoelectron spectroscopy and theoretical study on the electronic structure of UCl5- and UCl5.

We report a combined photoelectron spectroscopic and relativistic quantum chemistry study on gaseous UCl5(-) and UCl5. The UCl5(-) anion is produced using electrospray ionization and found to be highly electronically stable with an adiabatic electron binding energy of 4.76±0.03 eV, which also represents the electron affinity of the neutral UCl5 molecule. Theoretical investigations reveal that t...

Electronic structure and chemical bonding of divanadium-oxide clusters „V2Ox , xÄ3 – 7... from anion photoelectron spectroscopy

We report a photoelectron spectroscopic investigation of a series of divanadium-oxide clusters V2Ox 2 (x53 – 7). Well-resolved spectra were obtained at three photon energies ~355, 266, and 193 nm!, revealing the structural and electronic evolution as the number of oxygen atoms increases in the cluster series. A behavior of sequential oxidation was observed in V2Ox 2 for x up to 5: low binding e...
