Description
The reaction network in the neutron-deficient part of the nuclear chart around A$\sim$100 contains several nuclei of importance to astrophysical processes, such as the p-process. This work reports on the results from recent experimental studies of the radiative proton-capture reactions $^{112,114}$Cd(p,γ)$^{113,115}$In. Isotopically enriched $^{112}$Cd and $^{114}$Cd targets have been used for the determination of the cross sections, for proton beam energies residing inside the respective Gamow windows for each reaction. Two different techniques, the in-beam γ-ray spectroscopy and the activation method have been implemented, where the latter is considered mandatory to account for the presence of low-lying isomers in $^{113}$In (E$\approx$392 keV, $t_{1/2}\sim$100 min), and $^{115}$In (E$\approx$336 keV, $t_{1/2}\sim$4.5 h). Following the measurement of the cross sections, the astrophysical S factors have been subsequently deduced. The experimental results are compared to detailed Hauser-Feshbach theoretical calculations carried out with TALYS v1.95. The results are expected to shed light in the nucleosynthetic mechanisms of the p-process in neutron-deficient nuclei, where scarce experimental data exist.
