For modeling the extended reaction network of the process, the reaction rates are derived mainly from statistical model calculations, which are validated with experimental $\alpha $-induced reaction cross sections. In the present work, the key parameter of the statistical model is constrained by measuring cross sections a hundred times smaller than those in previous experiments, reaching down to the relevant stellar energies. It is expected that this work will reduce the uncertainty in the calculation of stellar production of these proton-rich nuclei.
