1. Isospin Breaking in Kaon Decays to Pions
Sammanfattning : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. LÄS MER
2. Meson Decay with Isospin Breaking At Two Loops
Sammanfattning : In all calculations done in this thesis, the evaluation of higher order quantum corrections has been central. In the first paper included in this thesis we have investigated the effects of finite volume meson propagators for quark-antiquark vacuum expectation value at two-loop level. LÄS MER
3. Mirror Nuclei - Isospin Symmetry Breaking in the Mass A=35 and A=51 Mirror Nuclei
Sammanfattning : High-spin states in the A=35 mirror nuclei 35Ar and 35Cl and A=51 mirror nuclei 51Fe and 51Mn were populated using fusion-evaporation reactions. The gamma rays were detected in the powerful Ge arrays Gammasphere and GASP, respectively, which operated in conjunction with ancillary detectors for evaporated particles. LÄS MER
4. Isospin symmetry breaking in the A = 51 mirror nuclei

5. A Trilogy of Mass A=61 : Superdeformed Structures, Exotic Decay, and Isospin Symmetry
Sammanfattning : Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. LÄS MER
