  1. 11. Mutual neutralisation reactions in atmospheric and industrial plasmas

    Författare :Mathias Poline; Richard D. Thomas; Jan Pettersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DESIREE; mutual neutralisation; ion storage; ion collisions; Physics; fysik;

    Sammanfattning : This thesis deals with experimental studies of electron transfer reactions between oppositely charged ions (mutual neutralisation). These were performed at the unique double electrostatic ion storage ring DESIREE at Stockholm University, which was put into full operation in 2017. LÄS MER

  2. 12. Laser Spectroscopic Investigations of Decay Properties in Stored Ions

    Författare :Peter Lundin; Sven Mannervik; Gillian Nave; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; fysik;

    Sammanfattning : Investigations and measurements of metastable states are in many ways very important. Spectroscopists, theorists and astrophysicists have all great interest and requirements regarding knowledge about such states and their properties. LÄS MER

  3. 13. Intake of fruit and vegetables in European children and their mothers, folate intake in Swedish children and health indicators : overweight, plasma homocysteine levels and school performance

    Författare :Agneta Yngve; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Folate status; MTHFR polymorphisms; BM; recommendations; dietary guidelines;

    Sammanfattning : An adequate fruit and vegetable intake provides essential nutrients and nutritive compounds and is considered an important part of a healthy lifestyle. Within the Pro Children project, an instrument for assessment of fruit and vegetable intake was developed, for use in nine European countries. LÄS MER

  4. 14. Determination of binary fission-fragment yields in the reaction 251Cf(nth, f) and Verification of nuclear reaction theory predictions of fission-fragment distributions in the reaction 238U(n, f)

    Författare :Evert Birgersson; Andreas Oberstedt; Stephan Oberstedt; Nicolae Carjan; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nuclear reactions; mass energy distributions; fission modes; fission-fragment spectroscopy; 251Cf nth; f ; 238U n; f ; Physics; Fysik; Fysik; Physics;

    Sammanfattning : Neutron-induced fission has been studied at different excitation energies of the compound nucleus by measurements on the two fissioning systems, 252Cf* and 239U*.For the first time, the light fission fragment yields from the reaction 251Cf(nth, f) have been measured with high resolution.

  5. 15. Laboratory studies of forbidden decay processes in stored ions

    Författare :Jonas Gurell; Sven Mannervik; Ahmed Al-Khalili; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik; fysik; Physics;

    Sammanfattning : Measurements of atomic and ionic data has been an active research area since the beginning of spectroscopic studies. The experimental data deduced from thesestudies are of great interest for our understanding of fundamental as well as applied physics. LÄS MER
