Obtaining accurate predictions of nuclear structure starting from the interaction between constituent protons and neutrons is a complex, computationally demanding problem. Accurate predictions depend on both short-range correlations as well as long-range clustering and collective dynamics, particularly when describing resonances and continuum states. We present state of the art methods used...
The study of radioactive isotopes is key to understanding the fundamental building blocks of matter. These investigations require state-of-the-art experimental stations, which exist only in select facilities around the world. The Gamma Ray Infrastructure For Fundamental Investigations of Nuclei (GRIFFIN), at the ISAC facility of TRIUMF is a powerful decay spectrometer that can be used to study...
Studies of tin isotopes are important for understanding the structure of singly-closed shell nuclei. The $^{116,118,120}$Sn isotopes are examples of even-even singly-closed shell nuclei close to the line of stability. Using $(n_\text{th},\gamma)$ reactions provides a comprehensive study of the level scheme of a nucleus. Despite many previous studies for stable tin isotopes, many nuclear levels...
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 that was
developed for nuclei close to stability. This has led to the concept of the evolution of nuclear
shell structure in exotic nuclei and the neutron-rich Ca isotopes are a key testing ground of
these theories. However, there...
A recent survey [1] of potential candidates for spherical vibrational motion [2] concluded that very few passed the criteria; of those that did, $^{98,100}$Ru were the most promising. However, in part this may have been due to the lack of detailed spectroscopic data for $^{98,100}$Ru. In order to remedy this, we have performed a high-statistics measurement of the β decay of $^{98,100}$Rh...
