The present contribution will give an overview of the photon strength function models developed to compensate for the lack of data for experimentally non-accessible nuclei. During this overview, phenomenological and microscopic approaches will be presented in light of their respective strengths. We will discuss more particularly the added value of microscopic approaches and the progressive...
Nuclear data in the quasi-continuum have increasingly garnered attention due to their central role in a vast array of applications spanning fields such as isotope production, fission and fusion reactor technologies, non-proliferation, and the fundamental sciences of nuclear astrophysics and nuclear structure. These data are characterized by the photon strength function (PSF) and nuclear level...
The photon strength functions (PSFs) and nuclear level density (NLD) are vital ingredients for the calculation of the photon interaction with nuclei, in particular, the reaction cross sections via the Hauser-Feshbach approach [1]. These cross sections are important, especially in nuclear astrophysics [2,3] and in the development of advanced nuclear technologies [4,5].
The role of the...
This presentation brings into focus $^{78,80}$Kr($\gamma$,$\gamma$’), $^{93}$Mo($\gamma$,n) and $^{90}$Zr($\gamma$,n) cross section measurements carried out using real photons at the H$\gamma$GS/TUNL facility. The overarching physics motivation for these experimental investigations is to advance knowledge on a forefront topic in nuclear astrophysics – the nucleosynthesis beyond Fe of the...
