Abstract: Outreach and engagement activities have been core functions of the Australian National University Department of Nuclear Physics for many years. Staff and students of the Department play an important role in educating local high school students, Australian Federal Government employees and the general public. As the ‘national’ university, we also accept a social responsibility to undertake endeavours that align with Australia’s broader strategic priorities. One of these is to make a positive, sustained contribution to the overall growth and development of our geographical neighbours. Here, I report on the existing program of local outreach at the ANU Heavy Ion Accelerator Facility, selected international engagement activities and comment on opportunities for future growth.

Abstract: We have performed measurements of sodium nuclear recoils in NaI:Tl crystals, following scattering by neutrons produced in a 7 Li(p,n) 7 Be reaction. Understanding the light output from such recoils, which is reduced relative to electrons of equivalent energy by the quenching factor, is critical to interpret dark matter experiments that search for nuclear scattering interactions. We have developed a spectrum-fitting methodology to extract the quenching factor from our measurements, and report quenching factors for nuclear recoil energies between 36 and 401 keV. Our results agree with other recent quenching factor measurements that use quasi-monoenergetic neutron sources. The new method will be applied in the future to the NaI:Tl crystals used in the SABRE experiment.

Abstract: Lantana canescens is popularly known in Brazil as "cidreirinha" or "chumbinho-branco". It is found in Pantanal biome and its flowers and leaves are used in traditional medicine to treat pain and inflammation. Information about this species is limited to the activity of isolated essential oils. Studies with different extracts, composition, and biological properties are still scarce. The objective of this study was to evaluate the anti-inflammatory and anti-hyperalgesic activity of the hydroethanolic extract of L. canescens aerial parts. The hydroethanolic extract L. canescens aerial parts (HELc) was analyzed using HPLC-DAD-EM. Male and female Swiss mice weighing 18-25 g were used in the in vivo assays. Acute toxicity was assessed (2000 mg/kg) anti-inflammatory activity through paw edema, mast cell degranulation and peritonitis, and anti-hyperalgesic activity through abdominal writhing assays induced by acetic acid and formalin sensitization, were evaluated using the doses of 3, 30 and 300 mg/kg. The phytochemical characterization of HELc confirmed the presence of glycosylated iridoids (theveside, theviridoside), verbascosides and flavonoids. The HELc did not present toxicity in the evaluated dose. HELc reduced formation of paw edema, degranulation of peritoneal mast cells and infiltration of polymorphonuclear cells into the animals peritoneal cavity. In addition, HELc decreased the number of abdominal writhing induced by acetic acid and the time of paw licking in the evaluation of formalin sensitization. These results confirm the anti-inflammatory and anti-hyperalgesic effects of hydroethanolic extract of L. canescens, validating the use of this plant in folk medicine.

Abstract: Electric monopole ( E 0) transitions are a highly sensitive probe of the charge distribution of an atomic nucleus. A large E 0 transition strength ( ρ 2 ( E 0)) is a clear indicator of nuclear shape coexistence. In the region between doubly magic 40 Ca and 56 Ni, E 0 transitions have never been observed in the Ti or Cr isotopes, nor in the heavier iron isotopes ( 56,58 Fe). We have performed the first measurements of the E 0 transitions in 52 Cr via conversion-electron and pair-conversion spectroscopy using the Super-e spectrometer at the Australian National University Heavy Ion Accelerator Facility. We present the first spectra obtained for 52 Cr, including the first observation of the E 0 transition from the first-excited 0 + state in 52 Cr, in both electron-positron pairs and conversion-electron spectroscopy. The preliminary values for the E 0 strength in the 1531keV 2 + → 2 + transition in 52 Cr is ρ 2 ( E 0) × 10 3 = 470(190), and for the 1728-keV 2 3 + → 2 1 + transition, it is ρ 2 ( E 0) 10 3 = 1800(1200). The large E 0 strengths observed are consistent with shape coexistence in this region. However, despite the relatively precise observation of the conversion-electron and electron-positron pair intensities, the E 0 strengths have large uncertainties. More precise determinations of relevant spectroscopic quantities, such as the state lifetimes and transition mixing ratios for mixed M 1 + E 2 transitions, are needed to determine the E 0 strength more precisely.

Abstract: The emergence of nuclear collectivity near doubly-magic 132 Sn was explored along the stable, eveneven 124−130 Te isotopes. Preliminary measurements of the B (E2 4 1 + → 2 1 + ) transition strengths are reported from Coulomb excitation experiments primarily aimed at measuring the g factors of the 4 1 + states. Isotopically enriched Te targets were excited by 198-205 MeV 58 Ni beams. A comparison of transition strengths obtained is made to large-scale shell-model calculations with successes and limitations discussed.
