Abstract
<blockquote>
One method of pursuit in our search for a more complete description of the spectroscopic properties of nuclei is through the isolation of specific or well-developed mechanisms. In the present work the characteristics of a weakly-bound nuclear single-particle orbital wave function, defined by its approach to the confining threshold, have been shown to be rooted within various nuclear phenomena. Most notably, the role of this geometric or so-called weak-binding behavior has been found to impact our descriptions of evolving single-particle orbitals, the presence or impact of 'bubble' nuclei, the locations of the particle driplines, and the origins of nuclear halo states. Future directions building upon and complementing this new insight will also be discussed.
