  1. 1. Neutron-Deuteron Scattering and Three-Body Interactions

    Författare :Philippe Mermod; Jan Blomgren; Steven Vigdor; Uppsala universitet; []
    Nyckelord :Nuclear physics; three-body force; neutron; deuteron; elastic scattering; angular distribution; Faddeev equations; Kärnfysik;

    Sammanfattning : High-precision differential cross section data of the neutron-deuteron elastic scattering reaction at 95 MeV are presented. The neutron-proton scattering differential cross section was also measured and used as a reference to allow an accurate absolute normalization of the neutron-deuteron data. LÄS MER

  2. 2. Theoretical and Numerical Studies of Efimov States

    Författare :Kajsa-My Blomdahl; Svante Jonsell; Michael Odelius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : In contrast to the classical case, the quantum three-body problem is amenable to qualitative analysis and, in some cases, even to analytic solutions. In 1970, Vitaly Efimov predicted that resonant two-body forces could give rise to a series of bound energy levels in three-particle systems. LÄS MER

  3. 3. Two-body Photodisintegration of ³He

    Författare :Martin Karlsson; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; differential cross sections; three-nucleon forces; MAX-lab; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:000;

    Sammanfattning : In a series of experiments using the tagged photon facility at MAX-lab located in Lund, Sweden, the two-body photodisintegration of ³He has been investigated in the photon energy range 14--32 MeV. Differential cross sections of the reaction ³He(g,d) have been measured by detecting deuterons and protons in silicon surface barrier detectors. LÄS MER

  4. 4. Algorithms and Interaction Potentials: phase density, surface tension and carbon dioxide

    Författare :Rasmus Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface tension; carbon dioxide; density of states; bicalutamide;

    Sammanfattning : This thesis is an amalgamation of articles (Papers I–V) by the author. We present a perturbation algorithm to calculate the phase density, and thus the partition function including its temperature dependence. LÄS MER
