Differential cross sections for transitions of known weak strength were measured with the (He3, t) reaction at 420 MeV on targets of C12, C13, O18, Mg26, Ni58, Ni60, Zr90, Sn118, Sn120, and Pb208. Using these data, it is shown that the proportionalities between strengths and cross sections for this probe follow simple trends as a function of mass number. These trends can be used to confidently determine Gamow-Teller strength distributions in nuclei for which the proportionality cannot be...[Show more]
