  2. 11. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Author : Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Abstract : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. READ MORE

  4. 12. Photoelectron Spectroscopy on HCl and DCl : Synchrotron Radiation Based Studies of Dissociation Dynamics

    Author : Florian Burmeister; Eckart Rühl; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Photoelectron spectroscopy; HCl; DCl; Dissociation dynamics; Born-Oppenheimer approximation; Synchrotron radiation; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Dissociation dynamics of the ionized molecules HCl and the deuterated system DCl has been studied in gas-phase using synchrotron based photoelectron spectroscopy (PES).The inner-valence "(4σ)-1" photoionization band for DCl and HCl was recorded using maximum resolution in order to probe an interference pattern between a dissociative and a bound electronic state.

  5. 13. Ultrafast dynamics of small quantum systems studied using electron-ion coincidence spectroscopy

    Author : Smita Ganguly; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coincidence spectroscopy; photodissociation dynamics; fragmentation reaction; MOLECULAR-BEAM; Cluster fission; Astrochemistry; Carbon dioxide CO2 ; ; Adamantane;

    Abstract : Studying how small quantum systems, like molecules and clusters, interact with X-rays is crucial to understanding the ultrafast processes that occur in nature on incredibly short timescales, ranging from femtoseconds to picoseconds. X-rays excite small quantum systems to unstable core hole states, leading to a cascade of phenomena, including Auger decay, nuclear rearrangement, and dissociation. READ MORE
