Two-nucleon stripping reactions induced by O in Fe and Ni at 80 MeV

Both the (¹⁶O, ¹⁴N) and (¹⁶O, ¹⁴C) reactions have been investigated on ⁵⁴Fe and ⁵⁸Ni target nuclei at 80 MeV incident energy. Both reactions are selective. The kinematical conditions have been found to act in two ways: (i) the high-spin states are enhanced and (ii) the states involving nucleons in the f- or p-shells are favoured. Three groups of T = 1 analog states have been located in ⁵⁶Ni and ⁶⁰Zn from a comparison of the two transfer reactions on the same target, and configuration assignments are attempted.
