Abstract
If the effective interaction for the (p, n) reaction were the free N-N force, and the free N-N force were the one pion exchange force, then the 12C(p,n)12N spectrum at 0º would look just like what is actually seen in a recent 120 MeV experiment (see fig. 1). Inverting the statement to claim that fig. 1 shows that the effective force is that of the one pion exchange potential would be overstating the case. It is, however, fair to say that new data in the 100–200 MeV energy range suggest an OPEP-like interaction with its characteristic spin-isospin operator, while at lower energy (p,n) spectra look qualitatively different with the spin independent IAS transition dominating the spectrum.
