Energy levels and branching ratios for the rp-process nucleus 25Si were determined from the reactions ⁹Be (²⁶Si, ²⁵Si) X and ⁹Be (²⁵Al, ²⁵Si) X using in-beam γ-ray spectroscopy with both high-efficiency and high-resolution detector arrays. Proton-unbound states at 3695(14) and 3802(11) keV were identified and assigned tentative spins and parities based on comparison to theory and the mirror nucleus. The ²⁴Al (p, γ) ²⁵Si reaction rate was calculated using the experimental states and states from charge-dependent USDA and USDB shell-model calculations with downward shifts of the 1s_1/2 proton orbital to account for the observed Thomas-Ehrman shift, leading to a factor of 10–100 increase in rate for the temperature region of 0.22 GK as compared to a previous calculation. These shifts may be applicable to neighboring nuclei, impacting the proton capture rates in this region of the chart.
