114. Invited Talk: Establishing the deformation characteristics of $^{66}$Ge

Nikita Bernier (University of the Western Cape)

Oral

The presence of both well-deformed prolate and oblate deformations is expected in the $A\approx70$ mass region because of the surprisingly large single-particle energy gaps at $N=34$. Nonetheless, oblate deformations in this region have mostly been inferred from rotational bands ($^{68}$Se [1]) or model-dependent decay measurements ($^{72}$Kr [2]). Only recently, Coulomb-excitation...

117. Invited Talk: Fine structure of the IVGDR in open-shell calcium isotopes

Prof. Iyabo Usman (University of the Witwatersrand)

Oral

This study aims to investigate fine structure of the isovector giant dipole resonance (IVGDR) in open-shell calcium isotopes and the effect of neutron excess in the sd-shell configurations. This will allow for disentangling the origin of damping mechanisms with considerations of different theoretical model calculations beyond Random Phase Approximation (RPA). The IVGDR was excited in 42,44Ca...

137. Understanding the Giant Dipole Resonance in Heavy Deformed Nuclei

Dr Lindsay Donaldson (iThemba Laboratory for Accelerator Based Sciences)

Oral

The IsoVector Giant Dipole Resonance (IVGDR) has far-reaching implications in nuclear physics. Experimental GDR data have been obtained using various techniques including photo-nuclear measurements with photons from Bremsstrahlung and quasi-monoenergetic photons from positron annihilation in flight and Laser Compton Scattering, but also using proton inelastic scattering. While good agreement...

120. Low-Energy Nuclear Physics Beamline at the iThemba LABS' Tandetron facility

Dr Kgashane Malatji (iThemba LABS)

19/04/2024, 10:40

Oral

The Low-energy Nuclear Astrophysics Beamline at the Tandetron facility, iThemba LABS, is designed to study indirectly radiative capture reactions through measurements of statistical properties. These reactions involve the capture of a charged particle, either a proton or an $\alpha$-particle, by the nucleus, resulting in the emission of gamma-ray photons. This process plays a pivotal role in...
