Description
Determination of the accurate values for gamma transitions, level scheme, nuclear level density and radiative strength functions is crucial in low-energy nuclear physics. Accurate experimental values of those parameters are very important for both fundamental and applied research. The two-step gamma cascades method, involving the detection of gamma coincidences following thermal (cold) neutron capture, i.e. the ($n_{th}$, 2$\gamma$) reaction, is a highly suitable technique for obtaining spectroscopic data and insights into level density and radiative strength functions. The experiment using an enriched $^{107}$Ag target was conducted at the PGAA station of the Budapest Neutron Centre, Budapest, Hungary, with thermal neutron beam, 3 HPGe detectors with appropriate shielding and acquisition system for coincidence measurements. In this talk, a brief overview of the method, some of the previous results, as well as the spectroscopic results for $^{108}$Ag nuclei obtained through $^{107}$Ag($n_{th}$,2$\gamma$) reaction will be presented.
