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 ^112,114Cd$(p,\gamma )$^113,115In. Experimental cross sections for the reactions have been measured for proton beam energies residing inside the respective Gamow windows for each reaction, using isotopically enriched ¹¹²Cd and ¹¹⁴Cd targets. Two different techniques, the in–beam γ–ray spectroscopy and the activation method have been employed, with the latter considered necessary to account for the presence of low–lying isomers in ¹¹³In ($E_{\gamma }\approx 392$ keV, $t_{1/2}\approx 100$ min), and ¹¹⁵In ($E_{\gamma }\approx 336$ keV, $t_{1/2}\approx 4.5$ h). Following the measurement of the total reaction cross sections, the astrophysical S factors have been additionally deduced. The experimental results are compared with Hauser–Feshbach theoretical calculations carried out with the most recent version of TALYS. The results are discussed in terms of their significance to the various parameters entering the models.
