2. [PLENARY TOPIC] Can octupole vibrations on the fine structure of the ISGMR in 208Pb enrich its energy scales?

Oral Presentation

This study aims to investigate the effects of the octupole vibrations on the fine structure of the isoscalar giant monopole resonance (ISGMR) in 208Pb. Quasi-Particle Model (QPM) based on the Skyrme Energy Density Functional approach was applied to allow for disentangling the origin of damping mechanisms beyond Random Phase Approximation (RPA) for this heavy doubly-magic nucleus. ISGMR was...

19. Physics-Informed Neural Networks for Bound States, Uncertainties, and Jost Function Construction.

Oral Presentation

The Jost function plays a central role in quantum few-body problems by providing direct access to the partial-wave S-matrix and its bound-state pole residues. These residues are related to nuclear vertex constants (NVCs) and asymptotic normalization constants (ANCs), which govern the asymptotic behavior of bound-state wave functions and the strength of reaction amplitudes. In this talk, I will...

21. Thermoluminescence investigation of dosimetric properties of a hydrothermally synthesized CuO compound for dosimetric applications

Oral Presentation

Research on the development of high-end luminescent materials, especially nanostructured phosphors (thermoluminescent (TL) materials), is of interest for application in radiation dosimetry. This study hydrothermally synthesized CuO and subsequently annealed it at different temperatures to modify its structural and intrinsic defect properties. X-ray diffraction showed that CuO was a pure...
