(t,3He) reactions onFe56,Fe58, andNi58

The ${}_{}{}^{56}{}_{}{}^{}$,58Fe and the ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$(t${,}^3$He) reactions have been studied at $E_{\mathrm{t}=25\mathrm{}}$ MeV. Differential cross sections have been measured in the angular range ${\theta }_{\mathrm{lab}=5.5\mathrm{}}$°–50°. The angular distributions have been compared with coupled-channels calculations and it is shown that $J^{\pi }$ assignments can be made to a large number of states in ${}_{}{}^{56}{}_{}{}^{}$,58Mn and in ${}_{}{}^{58}{}_{}{}^{}\mathrm{Co}$. This is the first comprehensive report of the use of the (t${,}^3$He) reaction as a tool for determining such $J^{\pi }$ assignments.
