Doctoral promotion Joss Wiese

In his thesis, Joss worked on unraveling signatures of molecular structure in photoelectron momentum distributions as they arise from the initial ionization step and subsequent electron-molecule interactions. His work contains both, pioneering experimental as well as theoretical results using a novel and highly efficient numerical approach, on the strong-field ionization of carbonyl sulfide, indole, and the indole-water cluster. Tomographic imaging methods were used to obtain three-dimensional photoelectron momentum distributions. Comparison with theory provided new insights into the ionization process and revealed how resonant and nonresonant ionization pathways differently encode the molecular structure. Furthermore dynamics of strong-field-driven photoelectron–molecule collisions were investigated in his thesis, shining light onto the impact of the nodal structure of the molecular orbital on molecular-frame photoelectron angular distributions (MFPADs).

We wish Joss Wiese the very best for his future career.
