Motivated by the proposed experiment 14N(d,2He) 14C, we study the final states which can be reached via the allowed Gamow-Teller mechanism. Much emphasis has been given in the past to the fact that the transition matrix element from the Jπ=1+, T=0 ground state of 14N to the Jπ=0+, T=1 ground state of 14C is very close to zero, despite the fact that all the quantum numbers are right for an allowed transition. We discuss this problem, but, in particular, focus on the excitations to final states with angular momenta 1+ and 2+. We note that the summed strength to the Jπ=2+, T=1 states, calculated with a wide variety of interactions, is significantly larger than that to the Jπ=1+, T=1 final states. We investigate the relative influences of the two-particle spin-orbit and tensor forces.
