Democracy Sausage with Mark Kenny: Responsibilities to protect
(Acast, 2023-11-07) Saul, Ben; Taflaga, Marija; Kenny, Mark
Newly appointed United Nations rapporteur on human rights and counter-terrorism Ben Saul joins Mark and Marija to discuss the Israel-Gaza conflict.
How does international humanitarian law apply to the Israel-Gaza conflict? What responsibilities do all parties have to protect civilians? And with influential voices both inside and outside of Israel calling for Prime Minister Benjamin Netanyahu to step aside, will his government last beyond the current crisis? On this episode of Democracy Sausage, United Nations Special Rapporteur on human rights and counter-terrorism Professor Ben Saul joins Professor Mark Kenny and Dr Marija Taflaga to discuss international law in the current conflict.
Democracy Sausage with Mark Kenny: Bob Hawke's complex legacy
(ACAST, 2023-11-14) Bramston, Troy; Taflaga, Marija; Kenny, Mark
Author and columnist Troy Bramston joins us to talk about the legacy and government of Bob Hawke, 40 years after his rise to the prime ministership.
Why does Prime Minister Anthony Albanese regard the Hawke government as a model for modern Labor? Would Hawke’s consensus-based approach be effective in a contemporary political environment? And what were his major regrets from his time in office? On this episode of Democracy Sausage, author of Bob Hawke: demons and destiny, Troy Bramston, joins Professor Mark Kenny and Dr Marija Taflaga to discuss Bob Hawke's complex legacy.

Energy dependence of p+232 Th fission mass distributions: Mass-asymmetric standard I and standard II modes, and multichance fission
(American Physical Society, 2022) Berriman, A. C.; Hinde, David; Jeung, D. Y.; Dasgupta, M.; Haba, H.; Tanaka, T.; Banerjee, K.; Banerjee, T.; Bezzina, L. T.; Buete, J.; Cook, K. J.; Parker-Steele, S.; Sengupta, C.; Simenel, C.; Simpson, E. C.; Stoyer, M. A.; Swinton-Bland, B. M. A.; Williams, E.
Background: The predominant mass-asymmetric fission of actinide nuclides occurs mainly through the so-
called standard I and standard II modes. Though understood to be caused by shape-dependent shell structures
encountered between the fission barrier deformation and scission, the most relevant shell gaps are still not firmly
established. The standard I mode had been associated with the spherical doubly magic 132 Sn, and thus the Z =
50 proton shell, but recently it has been proposed that standard I and standard II are associated with quadrupole
and octupole deformed gaps at Z = 52 and 56, respectively.
Purpose: We investigate how the relative probabilities of the standard I and standard II modes vary with
excitation energy near threshold, probing where the two modes bifurcate.
Methods: The Australian National University Heavy Ion Accelerator Facility and CUBE fission spectrometer
have been used to measure fission mass distributions for the p +232 Th reaction (forming 233 Pa) at closely spaced
bombarding energy intervals from 6.5 to 28 MeV.
Results: A model-independent analysis of the energy dependence of the shape of the mass-asymmetric peak
shows a strong dependence of the standard I and standard II relative probability on excitation energy near
threshold.
Conclusions: The results are consistent with the standard II mode having a lower fission barrier than standard
I in 233 Pa, with the latter increasing continually in relative probability above its barrier energy. It is concluded
that multichance fission, in particular last chance fission, plays a strong role in determining the observed energy
dependence of all fission modes.
