  2. 21. Studies of PWO Crystals and Simulations of the p̅p →Λ̅Λ, Λ̅Σ0 Reactions for the PANDA Experiment

    Author : Sophie Grape; Tord Johansson; Per-Erik Tegnér; Kai-Thomas Brinkmann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PANDA; antiproton; PWO; hyperon; lambda; simulation; polarisation; spin correlation; Nuclear physics; Kärnfysik; Physics; fysik;

    Abstract : The thesis comprises investigations of two topics related to the PANDA experiment. The first part is dedicated to energy resolution and light yield uniformity studies of PWO crystals for the electromagnetic calorimeter. The second part of the thesis is dedicated to simulation studies of the p̅p→Λ̅Λ and the p̅p→Λ̅Σ0 channels. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supraconductors; magnetic resonance; relaxation; spectroscopy; magnetic and optical properties; rare-gas clusters; Condensed matter:electronic structure; electrical; metal clusters; photoemission; synchrotron radiation; core-level spectroscopy; Auger decay; XPS; nano-particles; free clusters; egenskaper elektriska; spektroskopi; magnetisk resonans; magnetiska och optiska ; supraledare; Kondenserade materiens egenskaper:elektronstruktur;

    Abstract : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. READ MORE

  5. 23. PWO Crystal Measurements and Simulation Studies of Anti-Hyperon Polarisation for PANDA

  6. 24. Detailed photoemission studies of the prototype diluted magnetic semiconductor (Ga,Mn)As

    Author : Intikhab Ulfat; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Electronic structure; Ga; Mn As; Synchrotron radiation; MBE;

    Abstract : Magnetic semiconductors are materials that combine the key features needed in information technology, namely magnetism and controllable charge transport. The prospects of integrating these properties and of using the spin as informa-tion carrier have motivated large efforts to produce such materials for imple-mentation in future spin-based electronics.
