Isomeric yield ratios of 195m,gHg and 197m,gHg in the 196Hg(γ, n) and 198Hg(γ, n) reactions induced by bremsstrahlung energy within giant dipole resonance region

In this study, the isomeric yield ratio (IR) values of 196m,gAu and 195m,gHg in the 197Au(p,x) reaction within the proton energy range of 49.8–65.5 MeV were measured at the high-intensity proton linac facility (KOMAC) in Korea using an offline γ-ray spectrometric technique. Furthermore, the IR values of the above-mentioned products at different proton energies were calculated from the cross-sections based on the data in the TENDL-2019 library and are found to be higher than the experimental values. The IR values of 196m,gAu and 195m,gHg in the 197Au(p,x) reaction from the present and other works are compared with the similar literature data in the 197Au(γ,n), 196Hg(γ,n), 197Au(n,2n), 196Hg(n,2n), natPt(α,x) and natPt(3He,x) reactions to examine the role of compound nucleus spin, excitation energy, and input angular momentum.

The gamma beam system under construction at the ELI-NP facility in Romania is projected to give the nuclear physics community access to an experimental system providing a high-intensity, narrow bandwidth photon beam at variable energy. With high-efficiency detector systems in place, the experimental programme will have a strong potential for in-depth studies of rare stable isotopes originating from the astrophysical p-process. In particular, the neutron detection systems are already implemented through a dedicated 3He long neutron counter array, called ELIGANT-TN, that is completed and in use. In this mini-review, we will give a summary of the current status of existing (γ, n) cross-section data, as well as the methods to obtain them, and highlight the future potential to expand and improve such data using the ELI-NP instrumentation and beam-lines.
