  2. 1. High-Resolution Measurement of the 4He(g,n) Reaction in the Giant Resonance Region

    Author : Björn Nilsson; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tagged photons; photonuclear reactions; liquid helium; neutron detectors; liquid scintillators; giant resonances; angular distributions; differential cross sections; total cross sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:2003:Nilsson;

    Abstract : A comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintillator arrays.

  4. 2. Compton Scattering from the Deuteron at Low Energies

    Author : Magnus Lundin; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Compton scattering; photonuclear reactions; deuteron; differential cross sections; 50-70 MeV; polarizability; tagged photons; Nuclear physics; Kärnfysik; Fysicumarkivet A:2002:Lundin;

    Abstract : A series of three Compton scattering experiments on deuterium have been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 50 < Eg < 70 MeV tagged photons were scattered from a liquid deuterium target and detected simultaneously in three (10"x10") NaI detectors. READ MORE

  5. 3. The (γ,p) reaction in 16O and 18O at Eγ=50 - 70 MeV

    Author : Per Lilja; Lunds universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Two-body Photodisintegration of ³He

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

    Abstract : 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. READ MORE

  7. 5. Response of the PANDA electromagnetic calorimeter to photons with energies below 100 MeV

    Author : Klas Marcks von Würtemberg; Per-Erik Tegnér; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PANDA elecromagnetic calorimeter response PWO; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

    Abstract : Characteristics of the electromagnetic calorimeter of PANDA (anti-Proton ANnihilations at DArmstadt), one of the key experiments at FAIR, have been measured at the tagged photon beam facility at MAX-lab for 61 energies in the range 12-63 MeV. The tested detector array consisted of 5x5 PbWO4 (lead tungstate) crystals designed for the forward end-cap. READ MORE
