1. MCNPX Simulations for Neutron Cross Section Measurements
Sammanfattning : This thesis presents MCNPX simulations of the SCANDAL set-up used at the Theodor Svedberg Laboratory for neutron scattering cross-section measurements. The thesis describes processes and data important for the upcoming off-line data analysis. LÄS MER
2. The neutron-induced fission cross section of 233Pa : and the quest for clean and safe nuclear energy
Sammanfattning : 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. LÄS MER
3. Estimation and Testing in Panel Data with Cross-Section Dependence
Sammanfattning : This thesis makes a contribution the econometrics of panel data with cross-section dependence (CSD). It consists of five self-contained papers. LÄS MER
4. Life expectancy in Africa : A cross-national study
Sammanfattning : This thesis seeks to investigate the factors underlying the differences in life expectaocy in 28 low and middle-income African countries. The thesis is divided into two parts. LÄS MER
5. Λ-Λ hyperons: the road to estimate the production cross-section in protonproton collisions
Sammanfattning : In this study, we analyse the $\Lambda$-$\Lambda$ hyperon channel in proton-proton scattering, $pp \mapsto \Lambda\Lambda + K^+K^+, \,\,\Lambda\mapsto p+\pi^-$, with a proton beam energy of $4.5$ GeV using the High Acceptance Di-Electron Spectrometer (HADES) at GSI. LÄS MER
