- Augusto Maccchiavelli (Physics Division - ORNL)
The prompt gamma activation analysis (PGAA) facility has continuously been developed at Heinz Maier-Leibnitz Center (MLZ). Four Compton-suppressed HPGe detectors equipped with modern cooling systems and 64k digitals spectrometers have been used for analytical and nuclear-physics experiments in the strongest cold neutron beam of the world. The standard PGAA setup consists of a 60-% and a...
Understanding the structure of atomic nuclei at the extremes of the Segre chart is of
paramount importance in nuclear physics. In these nuclei, often termed exotic, new
shell closures may emerge, while others may disappear. A crucial region is formed by
the neutron rich Calcium isotopes, with striking appearances of new magic numbers at
N = 32 and N = 34.
Within the SEASTAR (Shell Evolution...
The emergence of collectivity in atomic nuclei is a primary research theme of the Australian National University Nuclear Structure Group. Through precision spectroscopy we aim to map emerging collectivity as valence nucleons are added to a doubly magic core, to elucidate the nature of weakly-collective nuclei, and to quantify the role of intruder configurations and shape-coexistence in...
Recent multi-messenger observations of explosive astronomical events are generating exciting new challenges for nuclear physics and force a rethinking of old paradigms. In particular, advanced, space-based telescopes have provided unprecedented insight into the production of chemical elements across the Galaxy, while the detection of massive neutron stars have ruled out a variety of hypotheses...
