  2. 16. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies

    Author : Joakim Nystrand; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion interactions; quark-gluon plasma; nuclear emulsion; multi-step avalanche chambers; particle production; transverse momentum distributions; intensity interferometry; nucleus-nucleus collisions; rapidity distributions; Physics; Fysik; Fysicumarkivet A:1996:Nystrand;

    Abstract : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. READ MORE

  4. 17. Rigidity of the Doubly-Magic 100Sn Core

    Author : Matej Lipoglavsek; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-beam gamma-ray spectrscopy; nuclear structure; fusion-evaporation reactions; nuclear shell model; quadrupole polarization charge; doubly-magic nucleus; Nuclear physics; Kärnfysik; Fysicumarkivet A:1998:Lipoglavšek;

    Abstract : The doubly magic nucleus 100Sn represents a crucial test for the nuclear shell model, which is a widely used model for a quantitative description of nuclei. Excited states in 100Sn are experimentally not accessible with present day techniques, but it is possible to gain insight into its structure by studying the properties of excited states of neighboring nuclei.

  5. 18. Development of New Monte Carlo Methods in Reactor Physics : Criticality, Non-Linear Steady-State and Burnup Problems

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; Nuclear physics; Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  6. 19. Studies of Nuclear Fuel by Means of Nuclear Spectroscopic Methods

    Author : Peter Jansson; Roland Carchon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; irradiated nuclear fuel; nuclear spectroscopy; tomography; safeguard; Strålningsvetenskap; Radiation biology; Strålningsbiologi; Kärnfysik; Nuclear Physics;

    Abstract : The increasing demand for characterization of nuclear fuel, both from an operator and authority point of view, motivates the development of new experimental and, preferable, non-destructive methods. In this thesis, some methods based on nuclear spectroscopic techniques are presented. READ MORE

  7. 20. Studies of Nuclear fuel by means of Nuclear Spectroscopy Methods

    Author : Peter Jansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik;

    Abstract : This paper which is a thesis for the title teknologie licentiat is a summary text of several works performed by the author regarding spectroscopic measurements on spent nuclear fuel. Methods for determining the decay heat of spent nuclear fuel by means of gammaray spectroscopy and for verifying the integrity of nuclear fuel by means of tomography is presented. READ MORE
