ISAC is the ISOL facility at TRIUMF where rare isotope beams for use in nuclear reaction investigations are created by bombarding solid targets with high energy particle beams. TRIUMF is enhancing its rare isotope production capabilities through a new scientific infrastructure known as the Advanced Rare IsotopE Laboratory (ARIEL). The low-energy transport section of the ARIEL expansion is...
One of the most prominent theories in describing nuclei is the nuclear shell model, which has accurately predicted many experimental trends in the atomic mass region of A=20-60 and beyond. One way to examine this model is by studying mirror nuclei-which have exchanged numbers of protons and neutrons. Differences between mirror nuclei's analogue nuclear levels and their decay patterns help in...
Shape coexistence in atomic nuclei, the existence of structures with different degrees of deformation in a very narrow energy range, is an exciting phenomenon that is present across the nuclidic chart. A recent theoretical study$^{[1]}$ using large scale shell model calculations predicted a well deformed prolate band at a low excitation energy in the doubly magic $^{78}$Ni nucleus which...
Experimental and theoretical studies of the germanium isotopes point increasingly toward exotic combinations of nuclear-structure effects, with indications of triaxiality, configuration mixing, and shape coexistence. A simple two-state mixing model has been used to describe 0$^+$ states in the even-even $^{72,74,76}$Ge isotopes, and reasonable agreement with experimental data from Coulomb...
Although the nuclear shell model does well to predict the structure of spherical nuclei, its ability to describe deformed nuclei far from shell closures is lacking. Models attempting to describe the structure of deformed nuclei, both from the microscopic and macroscopic perspective, require information on the excited energy levels of these nuclei in order to improve their predicting power....
The isotopes of tin are of great interest to the study of nuclear shell evolution, as they span from doubly magic $^{100}$Sn to $^{132}$Sn and beyond. Due to the highly stable closed shell of fifty protons, the even-even tin isotopes mid-shell between $N = 50$ and $N = 82$ are known to be spherical in their ground state. However, low-lying deformed states due to 2p-2h excitations across the...
