The p-process relies on an extended reaction network, which can be described theoretically by the Hauser-Feshbach statistical model, which in turn relies strongly on experimental data. To provide reliable data for <i>p</i>-nuclei, an experimental campaign at the Tandem Accelerator Laboratory of NCSR "Demokritos'', focusing on measurements of cross-sections in the<sup> 107,109</sup>Ag(p,γ)<sup>108,110</sup>Cd [3] and <sup>112</sup>Cd(p,γ)<sup>113</sup>In [4]<br>reactions was carried out. Both reactions were studied using a set of four HPGe detectors via the in-beam γ-ray spectroscopy, while for the latter the activation method was additionally employed to account for the population of a low-lying isomeric state. Total cross sections for proton beam energies lying inside the Gamow window for energies relevant to <i>p</i>-process nucleosynthesis were obtained for the first time. Experimental results are compared to Hauser-Feshbach calculations performed with the latest version of the TALYS code (v1.9) [5]. An overall good agreement has been achieved. These results provide important new input for the theoretical description of the<i> p</i>-process, but additionally for the origin of the cross-point <i>p</i>-nucleus <sup>113</sup>In.<div><br></div><div><b>References</b><br><br>[1] M.
