The first temperature-dependent relative self-absorption (TRSA) measurement was conducted at the Darmstadt High-Intensity Photon Setup (DHIPS) at the superconducting Darmstadt linear electron accelerator (S-DALINAC) on the nucleus $^{27}$Al using a bremsstrahlung photon beam with an endpoint energy of 5.5 MeV. This technique enables the separation of the natural linewidth of the nuclear...

In nuclear fission, a heavy nucleus splits and the fission fragments emerge spinning [2]. The isomeric yield ratio (IYR) i.e. the population frequency of an isomer, is know to be sensitive to the angular momentum of the fragment. Measuring the IYR can therefore give information about the initial sate of the fission fragments.
This work uses a technique to reach short lived isomeric states...

he Nuclear Level Density (NLD) and Gamma-ray strength function (GSF) are important quantities to study as they are inputs into the Hauser-Fesbach statistical model calculations which are used to predict reaction cross-sections. Once experimentally measured they can be used as inputs in codes such as TALYS [1] to calculate/constrain the $(n,\gamma)$ cross-sections. Thus, it is important to...

Targeted alpha therapy is a new modality of cancer treatment in which alpha-emitters are used to precisely target cancer cells; however the short range of alpha particles makes assessing the actual dose of radiation delivered to the cell challenging. PSMA-targeted $^{212}$Pb radionuclides have previously been clinically investigated for prostate cancer cell lines C4-2, PC3-PIP and PC3-Flu....

This study computationally evaluates a hybrid nuclear fuel cycle in which partially depleted fuel pebbles from a compact maritime Fluoride-salt-cooled High-temperature Reactor (FHR) are transferred to a larger terrestrial FHR for continued utilization. Neutronic behavior is analyzed using a high-fidelity Monte Carlo framework: the Hyper-Fidelity (HxF) tool models detailed depletion in the...

Radionuclides that decay with Meitner-Auger electrons are believed to have potential in targeted radionuclide therapy, due to their short ranges on the scale of the cellular nucleus with high precision dose delivery. To establish production routes, accurate nuclear data for optimization of irradiation and yield predictions are required. The Meitner-Auger emitter $^{193m}$Pt is of interest due...

In this gamma spectroscopy analysis, we aim to measure the spectroscopic quadrupole moments of excited states and electromagnetic transition rates in neutron-deficient 140Sm. The experimental data was collected during a Coulomb excitation experiment at ISOLDE in 2017, utilizing a 140Sm beam on a 208Pb target and the Miniball HPGe array alongside a CD particle detector.
The chain of samarium...

I will present my results from my work with Sr-82 that was conducted at LBNL fall 2025. Strontium 82 was produced, chemically separated and injected into mice. The biodistribution of Sr-82 was then measure both using PET scans and collection and gamma counting of organs after the end of the experiment. On the PET scans we can see a clear accumulation in the skeleton and head region, however...

The low-energy nuclear astrophysics beamline at the iThemba LABS 3-MV Tandetron facility enables the study of radiative capture reactions using proton and alpha beams. The setup can presently be instrumented with either up to twelve 3″×3″ LaBr₃:Ce detectors or six HPGe detectors (with associated BGO Compton-suppression shields), or with a combination of both detector types. To date, proton...

Heat-Pipe cooled Reactors (HPRs), which were originally intended for space applications, are of particular interest for remote/autonomous operations as their designs are simple, compact, and transportable. Historically most HPR designs produce only limited thermal power in the kilowatt range and/or utilize highly enriched fuel. This work investigated how reactor design principles can be used...

Reliable fission yield data are essential input for reactor depletion simulations, decay heat predictions, and fuel cycle assessments. The high accuracy of these data is particularly important for decommissioning-related analyzes involving the characterization and subsequent handling procedures of irradiated materials. The statistical description of fission fragment de-excitation is based...

The Photon Strength Function (PSF) database hosted by the IAEA [1,2] provides both experimental data and theoretical calculations. Experimental PSF data extracted using the Oslo method were compared to two theoretical models recommended on the IAEA database website. One model is purely phenomenological (SMLO) while the other is based on microscopic calculations (D1M-QRPA).
For all the...

The overall goal of nuclear astrophysics is to understand the creation of the elements in the universe and the nucleosynthesis processes that are involved. Nuclear Level Densities (NLD) are used as inputs to calculate reaction rates for nuclear reactions that occur in different stellar environments. NLDs represent the number of excited energy levels present in a nucleus at a specific...

Between the 1960s and early 1980s, the United States undertook the world’s largest nuclear power construction program. Early projects benefited from declining construction costs, making nuclear power economically competitive with fossil alternatives. From the early 1970s and onward, however, overnight construction costs (OCC) escalated rapidly, coinciding with regulatory tightening, high...

In this poster, we present the results of our previous experimental study and discuss a future theoretical approach. The aim of our research is to achieve a comprehensive understanding of the Big Bang Nucleosynthesis (BBN) process and to potentially resolve the Cosmological Lithium Problem (CLP). The CLP is a well-known issue in astrophysics, referring to the overestimation of the primordial...
