    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 16O γ; Photonuclear reactions; 18O γ; p ; E= 50 - 70 MeV; tagged photons; differential cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2004:Lilja;

    Sammanfattning : A measurement of the reactions 16O(γ,p)15N and 18O(γ,p)17N have been made with tagged photons in the energy range Eγ ≈ 50 – 70 MeV. The protons have been detected in ΔE-E telescopes with silicon strip detectors as ΔE detectors and HPGe crystals as E detectors. LÄS MER

  3. 2. High-resolution measurement of the ¹⁶O(γ,pn) reaction

    Författare :Lennart Isaksson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pn ; E_gamma = 67-76 MeV; resolved states; cross-sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:1996:Isaksson; 16O gamma; Photonuclear reaction;

    Sammanfattning : The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. LÄS MER

  4. 3. Effective Field Theory and One-proton Halo Nuclei

    Författare :EMIL RYBERG; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiative capture; halo nuclei; effective field theory; nuclear physics; charge radius;

    Sammanfattning : In this thesis we present formalism for treating one-proton halo nuclei in effective field theory. Halo nuclei are loosely bound systems consisting of a core plus valence nucleon(s). In so called Halo, or Cluster, effective field theory, the core of the halo nucleus is treated as a structureless, effective degree-of-freedom. LÄS MER
