A current view of nuclear structure: “exotic” versus “stable” nuclei

Thursday 17 January 2019, 1.00PM

Speaker(s): John L. Wood, Georgia Institute of Technology

Nuclear structure is entering a new era, with broad and detailed study of long chains of isotopes, and new reaches to far from stability (FFS) nuclei. The FFS studies are being promoted in part by claims that the fundamental shell structure, established in “stable” nuclei, undergoes major changes in “exotic” nuclei. To establish an unequivocal view of structure needs detailed and multiple spectroscopic probes: this is not achievable in FFS studies, i.e., in exotic nuclei. Facilities that permit detailed studies with a wide variety of spectroscopies are limited to the study of near stable nuclei; it is critical that activities at these facilities (even their existence) do not become overshadowed by the push to FFS studies.

A view of the current key questions in nuclear structure, especially what is meant by “shell” structure in exotic nuclei vs. stable nuclei, will be presented. The connection of these questions to theory will be discussed.
