  1. 1. Neutron induced light-ion production from iron and bismuth at 175 MeV

    Författare :Riccardo Bevilacqua; Stephan Pomp; Magnus Wolke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutron induced reactions; light-ion production; quasi-monoenergetic neutron beam; nuclear data; accelerator driven systems; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Sammanfattning : Light-ions (protons, deuterons, tritons, 3He and α articles) production in the interaction of 175 MeV neutrons with iron and bismuth has been measured using the Medley setup at the The Svedberg Laboratory (TSL) in Uppsala. These measurements have been conducted in the frame of an international collaboration whose aim is to provide the scientific community with new nuclear data of interest for the development of Accelerator Driven Systems, in the range of 20 to 200 MeV.

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

    Författare :Pawel Nadel-Turonski; Leif Nilsson; Adriaan van den Berg; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Measurements of Neutron-induced Nuclear Reactions for More Precise Standard Cross Sections and Correlated Fission Properties

    Författare :Kaj Jansson; Cecilia Gustavsson; Stephan Pomp; Alexander Prokofiev; Ali Al-Adili; Fanny Farget; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cross Section; Fission; Neutron-induced reactions; Simulation; VERDI; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : It is difficult to underestimate the importance of neutron cross section standards in the nuclear data field. Accurate and precise standards are prerequisites for measuring neutron cross sections. Two different projects are presented here with the aim of improving on neutron standards. LÄS MER

  5. 4. Fast neutron dosimetry : a study of basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections

    Författare :Jonas Söderberg; Lennart Lindborg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Basic dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Elementary pencil-beam dose distributions taking into account transport of all relevant types of released charged particles (protons, deuterons, tritons, 3He and a particles) were calculated and used to derive several absorbed dose distributions.

  7. 5. Fragment Mass Distributions in Neutron-Induced Fission of 232Th and 238U from 10 to 60 MeV

    Författare :Vasily Simutkin; Stephan Pomp; Franz-Josef Hambsch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ADS; neutron-induced fission; intermediate neutron energies; fragment mass yield; Nuclear physics; Kärnfysik; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Since its discovery, the phenomenon of nuclear fission is the object of extensive theoretical and experimental studies. However, we are still far from a complete understanding of the fission process. LÄS MER
