Description

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 have been conflicting results from various experiments as to the
true nature of a sub-shell closure for neutron-rich nuclei around 52Ca. In June of 2018, an
experiment was performed at the ISAC facility of TRIUMF; 52K was delivered to the GRIFFIN
gamma-ray spectrometer which was paired with the beta-tagger SCEPTAR and the Zero Degree
Scintillator auxiliary detectors. Using this powerful combination of detectors, the level
scheme of 52Ca populated following the β-decay of 52K has been constructed. Preliminary
results from the analysis will be presented and discussed in the context of an N=32 shell
closure in neutron-rich nuclei.
