The tin isotopic chain with its magic 50 proton closed shell is a benchmark for models of nuclear structure. While the neutron-rich tin nuclei around the magic 82 neutron shell play an important role in the rapid-capture nuclear process, the mid-shell region of the tin isotopes can display collective phenomena known as shape coexistence [1]; for example, in $^{116}$Sn$_{66}$ deformed bands...
Motivated by fundamental symmetry tests, a measure of large electric dipole moment (EDM) would represent a clear signal of the violation of the CP symmetries. This observation highlights the imbalance in the matter and antimatter observed in our Universe. Since the best theory for particle physics: the Standard Model (SM) of particles predicts an EDM lower ($10^{-30}$) than the experimental...
Nuclei away from the line of stability have been found to demonstrate behavior that is inconsistent with the traditional magic numbers of the spherical shell model. This has led to the concept of the evolution of nuclear shell structure in exotic nuclei, and the neutron-rich calcium isotopes are a key testing ground of these theories; there have been conflicting results from various...
Many outstanding fundamental topics in nuclear physics are addressed in the NSERC Subatomic Physics Long Range Plan. For several of these critical research drivers, such as " How does nuclear structure emerge from nuclear forces and ultimately from quarks and gluons?", gamma-ray spectroscopy is the investigative technique of choice. However, analysis of data from large-scale gamma-ray...
