2. 1. The neutron-induced fission cross section of 233Pa : and the quest for clean and safe nuclear energy

   Author : Fredrik Tovesson; Andreas Oberstedt; Dietrich Hilscher; Örebro universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Fysik; fission; cross section; Pa-233; U-233; fysik; Physics; Fysik; Fysik; Physics;

   Abstract : Neutron-induced fission of 233Pa has been investigated between 1.0 and 8.5 MeV, and the reaction cross section was determined. Due to the short half-life of 233Pa for β-decay, fission events from the daughter product 233U affect the analysis of the protactinium experiment. READ MORE

5. 3. Nucleon-Induced Fission Cross Sections of Heavy Nuclei in the Intermediate Energy Region

   Author : Alexander Prokofiev; Uppsala universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Fission; cross section; n; f reaction; p; intermediate energy; database; nuclear reaction; neutron; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

   Abstract : Fission is the most important nuclear reaction for society at large today due to its use in energy production. However, this has raised the problem of how to treat the long-lived radioactive waste from nuclear reactors. READ MORE

6. 4. Dosimetry and radiation quality in fast-neutron radiation therapy : A study of radiation quality and basic dosimetric properties of fast-neutrons for external beam radiotherapy and problems associated with corrections of measured charged particle cross-sections

   Author : Jonas Söderberg; Gudrun Alm Carlsson; Crister Ceberg; Linköpings universitet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neutron; Dosimetry; Radiotherapy; Monte Carlo; Microdosimetry; Cross-section; RBE; LET; Energy-loss corrections; Radiological physics; Radiofysik;

   Abstract : The dosimetric properties of fast-neutron beams with energies ≤80 MeV were explored using Monte Carlo techniques. Taking into account transport of all relevant types of released charged particles (electrons, protons, deuterons, tritons, 3He and α particles) pencil-beam dose distributions were derived and used to calculate absorbed dose distributions.

7. 5. Measurements of the Standard Model Higgs boson cross sections in the WW* decay mode with the ATLAS experiment

   Author : P. Edvin Sidebo; Jonas Strandberg; Markus Klute; KTH; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; p p: colliding beams; Higgs particle: hadroproduction; Higgs particle: decay; cross section: measured; High energy physics: experimental; Timing detectors; p p: scattering; ATLAS; Cern LHC Coll; Fysik; Physics;

   Abstract : This thesis summarises measurements of the Standard Model Higgs boson production cross sections based on proton–proton collision data at √s = 13 TeV produced by the Large Hadron Collider at CERN. By analysing data collected during 2015 and 2016 by the ATLAS experiment, corresponding to an integrated luminosity of 36 fb−1, the Higgs boson gluon–gluon fusion and vector boson fusion production cross sections are measured in the WW* decay mode.
