1. Making predictions using χEFT
Sammanfattning : In this thesis we explore the merits of chiral effective field theory (χEFT) as a model for low-energy nuclear physics. χEFT is an effective field theory based on quantum chromo dynamics (QCD) describing low-energy interactions of nucleons and pions. LÄS MER
2. Few nucleon systems at the exotic doubly magic region 132Sn
Sammanfattning : The low-energy structure of 133Sn, 133Sb and 133Te has been studied. The levels of 133Sn were populated in the β-delayed neutron decay of 134In at the ISOLDE PS-Booster (PSB) mass-separator facility at CERN. The single-neutron states p3/2, h9/2 and f5/2 in 133Sn were identified at 853.7, 1560. LÄS MER
3. The data perspective on chiral effective field theory
Sammanfattning : The scientific method implies a dynamical relationship between experiment and theory. Indeed, experimental results are understood through theories, which themselves are of less value until confronted with experiment. LÄS MER
4. Nucleon-Nucleon Scattering in a Wave-Packet Formalism
Sammanfattning : In this thesis I analyse the prospect of leveraging statistical analyses of the strong nuclear interaction by using the wave-packet continuum discretisation (WPCD) method to efficiently compute nucleon-nucleon (NN) scattering observables on a graphics processing unit (GPU). The WPCD method gives approximate solutions to the S-matrix at multiple scattering energies at the cost of a single eigendecomposition of the NN channel Hamiltonian. LÄS MER
