2. 1. Meson production in pd collisions

   Author : Karin Schönning; Jozef Zlomanczuk; Bo Höistad; Susan Schadmand; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; meson production; measured angular distribution; total cross section; polarisation; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

   Abstract : Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. READ MORE

4. 2. Neutron-Deuteron Scattering and Three-Body Interactions

   Author : Philippe Mermod; Jan Blomgren; Steven Vigdor; Uppsala universitet; []
   Keywords : Nuclear physics; three-body force; neutron; deuteron; elastic scattering; angular distribution; Faddeev equations; Kärnfysik;

   Abstract : High-precision differential cross section data of the neutron-deuteron elastic scattering reaction at 95 MeV are presented. The neutron-proton scattering differential cross section was also measured and used as a reference to allow an accurate absolute normalization of the neutron-deuteron data. READ MORE

5. 3. Production of photoneutron beams and radionuclides by photonuclear reactions using a 50 MeV racetrack microtron

   Author : Bo Nordell; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neutron therapy; Photoneutron spectrum; Bremsstrahlung; Angular distribution; Carbon 11; Iodine 123;

   Abstract : The feasibility of using electrons accelerated by a 50 MeV racetrack microtron to generate a mixed beam of neutrons and photons for radiation therapy and for production of radionuclides has been investigated.To develop target systems for these purposes the angular distribution and yield of bremsstrahlung from different targets have been studied theoretically.

6. 4. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

   Author : Johan Mårtensson; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

   Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE

7. 5. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique

   Author : Karin Andgren; Bo Cederwall; Paul Nolan; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion reactions; multi-detector arrays; recoil separator; in-beam gamma-ray spectroscopy; high spin states; lifetime measurements; recoil-decay tagging; nuclear shape; Nuclear physics; Kärnfysik;

   Abstract : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. READ MORE
