我们确定了32S（p,p）中J(pi) = 1/2(+), T = 3/2的共振能量为E(p) = 3374.7+/-0.8 keV。这与Abbondanno等人先前接受的E(p) = 3370+/-1 keV的值不一致[Nuovo Cimento 70A， 391(1970)]，并解决了最近观测到的等压多重质量方程的意外偏差所引起的问题。这种共振在校准来自33Ar和32Ar的β -延迟质子光谱中也很重要，我们的发现可能会修正之前的结论。
We have determined the energy of the J(pi) = 1/2(+), T = 3/2 resonance in 32S(p,p) to be E(p) = 3374.7+/-0.8 keV. This disagrees with the previously accepted value of E(p) = 3370+/-1 keV by Abbondanno et al. [Nuovo Cimento 70A, 391 (1970)] and solves a problem raised by recent observations of unexpected deviations from the isobaric multiplet mass equation. This resonance is also important in calibrating the beta-delayed proton spectra from 33Ar and 32Ar, and our findings may modify previous conclusions.
