  1. 1. Experimental Studies of Neutron Emission Induced by Heavy-Ion Scattering

    Author : Pawel Nadel-Turonski; Leif Nilsson; Adriaan van den Berg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; inelastic scattering; heavy ions; position sensitive silicon detectors; storage ring; cluster-jet target; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : A beam of 250A MeV 17O ions was scattered from argon and xenon targets. The large excess of fast neutrons compared with statistical model calculations that was observed earlier for xenon, was confirmed and found for argon as well. READ MORE

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

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

    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. Electron impact dissociation of molecular ions at CRYRING

    Author : Ahmed Al-Khalili; Ronald A Phaneuf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : In this thesis, the electron impact dissociation of molecular ions has been studied using the ion storage ring CRYRING at Manne Siegbahn Laboratory in Stockholm, Sweden. The electron impact dissociation of molecular ions occurs via many processes, which lead to different charge states of the product fragments. READ MORE

  4. 4. Late Quaternary climate and environmental change in the summer rainfall region of South Africa : A study using trees and wetland peat cores as natural archives

    Author : Elin Norström; Karin Holmgren; Michael Meadows; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paleoclimate; Late Quaternary; pollen; stable isotopes; diatoms; phytoliths; dendroclimatology; South Africa; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : This thesis contributes with information on past climate and environmental changes in South Africa’s summer rainfall region. The study is based on multi-proxy analyses on wetland peat cores and analyses of stable isotope composition (δ13C, δ18O) and wood anatomy in cross sections from subtropical trees (Breonadia salicina).

  5. 5. Computational Fluid Dynamics of Processes in Iron Ore Grate-Kiln Plants

    Author : Per Burström; Xue-Song Bai; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Computational Fluid Dynamics (CFD) approaches have been developed to studypollution reduction in the manufacturing phase and heat transfer in the packed beds of iron ore pellets. CFD is a versatile tool that can be applied to study numerous problems in fluid mechanics. READ MORE
