1. Three-nucleon forces in nuclear physics simulations
Sammanfattning : The aim of this licentiate thesis is to evaluate the normal-ordered two-body (NO2B)-approximation as a computationally promising way to incorporate realistic three-nucleon forces (3NFs) in nuclear many-body simulations using the no-core-shell-model. The existence and importance of 3NFs is predicted in chiral effective field theories of the strong-nuclear force. LÄS MER
2. Approximating the Three-Nucleon Continuum
Sammanfattning : Three-nucleon forces (3NFs) are necessary to accurately describe the properties of atomic nuclei. These forces arise naturally together with two-nucleon forces (2NFs) when constructing nuclear interactions using chiral effective field theories (χEFTs) of quantum chromodynamics. LÄS MER
3. Two-body Photodisintegration of ³He
Sammanfattning : In a series of experiments using the tagged photon facility at MAX-lab located in Lund, Sweden, the two-body photodisintegration of ³He has been investigated in the photon energy range 14--32 MeV. Differential cross sections of the reaction ³He(g,d) have been measured by detecting deuterons and protons in silicon surface barrier detectors. LÄS MER
4. JupiterNCSM: A Pantheon of Nuclear Physics —an implementation of three-nucleon forces in the no-core shell model—
Sammanfattning : It is well established that three-nucleon forces (3NFs) are necessary for achieving realistic and accurate descriptions of atomic nuclei. In particular, such forces arisenaturally when using chiral effective field theories (χEFT). LÄS MER
5. Neutron-Deuteron Scattering and Three-Body Interactions
Sammanfattning : 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. LÄS MER
