Neutron deficient nuclei near Z=82 exhibit one of the most extensive manifestations of shape coexistence across nuclear chart [1]. In the even-even mercury isotopes, $^{182-188}$Hg, Coulomb excitation experiments have provided a sensitive probe to determine the E2 matrix elements, giving information on the nature of the deformation for nuclear states [2]. Precise measurements of absolute and...

The nuclear kinetic density is a fundamental, non-observable quantity in density functional theory (DFT) dependent on the nonlocal nuclear density. With the ability to compute the nonlocal nuclear density in the ab initio no-core shell model approach (NCSM), we may provide insights about nuclear structure by comparing center of mass (COM) removal procedures, which can improve the precision of...

Excited states in $^{28}$Mg were studied in an experiment at the ISAC-II facility at TRIUMF to investigate the evolution of nuclear shells and search for evidence of the lowering in energy of $pf$ negative parity orbitals predicted near the $N=20$ 'island of inversion'. For the first time $^{28}$Mg was investigated using a fusion-evaporation reaction [12C($^{18}$O,2p)$^{28}$Mg], leading to...

The nature of the nuclear pairing condensates in heavy nuclei, specifically neutron-proton (spin-triplet), versus identical-particle (spin-singlet) pairing has been an active area of research for quite some time.

In this work, we probe three candidates that should display spin-triplet, spin-singlet, and mixed-spin pairing. Using theoretical approaches such as the gradient method and symmetry... -

Neutron-rich nuclei near the N=50 closed shell are of particular interest for their role in the rapid neutron capture process (r-process) of heavy element nucleosynthesis. Nuclear properties such as neutron capture rates and spectroscopic properties are crucial inputs to constrain theoretical models and improve their predictive power to properties of exotic, neutron-rich isotopes where little...
