1. 1. The Bloch-Messiah theorem and its application to overlaps

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Frieder Selisko; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. LÄS MER

3. 2. Assessment of the Capability for Vetoing Beta-Decay Events in the Lundium Decay Station

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Tanvir Sayed; [2022]
   Nyckelord :Radioactivity; Decays; Radiation; Ionisation; Superheavies; Exotic isotopes; Decay spectroscopy; Semiconductors; Silicon-Strip Detectors; Lundium; Vetoing; Electron spread; Particle identification; Physics and Astronomy;

   Sammanfattning : Alpha decay spectroscopy using the latest and most sensitive detector setup as well as fast sampling read-out electronics has become very important for discovery and analysis of short-lived nuclei created in collision experiments in the laboratory. The Nuclear Structure Group in Lund is currently developing the Lundium Decay Station for use in comprehensive nuclear spectroscopy of decays for rare isotopes, particularly in the heavy & superheavy region.

4. 3. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Josephine Lindsey-Clark; [2021]
   Nyckelord :Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

   Sammanfattning : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. LÄS MER

5. 4. Nucleosynthesis in accretion disks around black holes

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Neige Frankel; [2017]
   Nyckelord :accretion disk; Nucleosynthesis; black hole; high energy; white dwarf tidal disruption; Physics and Astronomy;

   Sammanfattning : Nucleosynthesis is the mechanism which produces new elements in nuclear reactions. Nuclear reaction rates are highly temperature dependant, and nuclear reactions take place in very hot environments. Current theories predict that the light elements such as hydrogen and helium were produced during the Big Bang. LÄS MER

7. 5. Residential wood combustion, cancer risk frequency and costs in Sweden : A review of instruments using the MCA methodology

   Master-uppsats, KTH/Industriell ekologi

   Författare :Matilda Watz; [2017]
   Nyckelord :Air pollution; Socioeconomic costs; PM2.5; B a P; MCA; Environmental management; Environmental policy; Residential wood combustion; Luftföroreningar; Samhällsekonomiska kostnader; PM2.5; B a P; MCA; Miljömanagement; Miljöpolicy; Vedeldning;

   Sammanfattning : Air pollution cause approximately 5000 premature deaths in Sweden each year. Residential wood combustion of solid biomass (RWC) is responsible for at least 1000 based on a relative risk coefficient of 17 % per 10 μg/m3 exposure. LÄS MER
