Research activities using High Intensity Gamma-ray Source facility at TUNL*

Current ongoing research activities using the High Intensity Gamma-ray source (HI$\gamma$S) facility at TUNL will be presented. Experimental setup, analysis, and results will be focused on the following low-energy activities: (1) Mono-energetic photon induced $^{235}$U/$^{239}$Pu fission cross-section ratio measurements at $E_{\gamma}$ = 8 - 13 MeV, (2) Mono-energetic photon induced Fission-Product-Yield measurements on $^{235}$U, $^{238}$U, and $^{239}$Pu at $E_{\gamma}$ = 11.0 and 13.0 MeV, and (3) Systematic study of Pygmy Dipole Resonances in nuclei across the nuclear landscape.
