    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Svante Jonsell; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; beta decay; neutrino mass; HeH ; nonadiabatic effects; pionic hydrogen; pion mass; three-body resonances; antihydrogen; annihilation; cold collisions; Bose- Einstein condensation; Kvantkemi; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; Quantum Chemistry; kvantkemi;

    Abstract : Some cases in which the interpretation of experiments in nuclear, particle, and low temperature physics requires understanding of molecular effects have been studied.Neutrino-mass determination from β decay of T2 requires knowledge of the energy loss due to molecular excitations of the daughter HeT+ molecule.

  2. 2. Heavy particle interference and diffraction in fast electron transfer collisions

    University dissertation from Stockholm : Department of Physics, Stockholm University

    Author : Magnus Gudmundsson; Henrik Cederquist; Henning Schmidt; Erik Horsdal; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics; fysik;

    Abstract : This thesis presents experimental results from the synchrotron cooler and storage ring CRYRING on charge transfer processes in fast electron transfer collisions using high-resolution cold target recoil-ion momentum spectroscopy. The main focus of these studies was to investigate a key concept of quantum mechanics: the wave-particle duality. READ MORE

  3. 3. Circumstellar Debris Disks : Observational Studies of Cold Dust and Gas Emission in Planetary Nurseries

    University dissertation from Stockholm : Department of Astronomy, Stockholm University

    Author : Ricky Nilsson; Alexis Brandeker; Mark Wyatt; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; circumstellar disks; debris disks; Kuiper belts; planet formation; submillimeter imaging; photometry; coronagraphy; integral-field spectroscopy; Astronomy; astronomi;

    Abstract : Planetary systems form in disks of gas and dust surrounding newborn stars. The young circumstellar environment is characterized by frequent collisions between rocky bodies, leading to a continuous production of small dust grains. READ MORE

  4. 4. Synchrotron Radiation, Adsorption Isotherms and the Large Hadron Collider Vacuum System

    University dissertation from Stockholm : Department of Astronomy, Stockholm University

    Author : Erik Wallén; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; H2; photon stimulated desorption; CO2; cryotrapping; liquid He; accelerators; isotherms; CH4; He; Monte Carlo simulations; synchrotron radiation; vacuum; CO; physisorption;

    Abstract : In circular particle accelerators and storage rings with relativistic beams of particles, e.g. electrons or protons, the vacuum performance of the accelerator is determined by the outgassing from the walls of the beam vacuum chamber. READ MORE

  5. 5. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ilka. A. D. Engelhardt; Anders Eriksson; Ingrid Mann; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. READ MORE
