通过28si (p,t) 26si反应研究了25al (p,γ) 26si中的几个共振。利用分段环形探测器阵列测量了Triton的能量和角分布。另外一个硅探测器阵列被用来同时探测26 Si中超过质子阈值的态衰变所发射的同步质子，以确定分支比。实验证实5927±4 keV的共振是质子阈值以上的第一个l = 0状态，质子分支比与1一致。
Several resonances in 25 Al(p,γ) 26 Si have been studied via the 28 Si(p,t) 26 Si reaction. Triton energies and angular distributions were measured using a segmented annular detector array. An additional silicon detector array was used to simultaneously detect the coincident protons emitted from the decay of states in 26 Si above the proton threshold in order to determine branching ratios. A resonance at 5927 ± 4 keV has been experimentally confirmed as the first l = 0 state above the proton threshold, with a proton branching ratio consistent with one.
