1. X-ray emission from supernova shock waves
Sammanfattning : A theoretical study of the interaction between supernovae and their surroundings is presented.Supernovae are the endpoint of the life of massive stars, and are the dominant contributors to the chemical evolution of the Universe. During its life a massive star greatly modifies its environment. LÄS MER
2. X-ray emission spectra of free molecules
Sammanfattning : .... LÄS MER
3. Soft X-ray Emission Spectroscopy of Liquids and Lithium Battery Materials
Sammanfattning : Lithium ion insertion into electrode materials is commonly used in rechargeable battery technology. The insertion implies changes in both the crystal structure and the electronic structure of the electrode material. LÄS MER
4. Resonant Soft X-Ray Emission Spectroscopy of Vanadium Oxides and Related Compounds
Sammanfattning : This thesis addresses the electronic structure of vanadium and copper oxides using soft X-ray absorption (SXA) spectroscopy and resonant inelastic X-ray scattering (RIXS) at high brightness synchrotron radiation sources. In RIXS incident photons, tuned to the energy of specific absorption resonances, are inelastically scattered leaving behind a low energy valence excitation in the system studied. LÄS MER
5. A soft X-ray emission study of the electronic structure of molecules
Sammanfattning : The electronic structure of molecules has been studied with soft x-ray emission (SXE)spectroscopy. The parity selection rule for electronic transitions using resonant excitation has been verified for homonuclear diatomic molecules by studying N2 and O2. LÄS MER
