Stripping effects in the reactions C12(He3, p)N14 and C12(He3, d)N13 at 13.9 Mev

Angular distributions have been measured for the reactions C12(He3, p)N14 and C12(He3, d)N13 using the cyclotron 14-Mev He3 beam. Assuming that the (He3, p) reaction proceeds by the stripping of a deuteron in either its singlet or triplet state from the He3 nucleus, reasonable fits to the angular distributions were obtained using a [jL(Qr0)]2 dependence. For the transitions to the 1+, T=0 ground and second excited states of N14, L=2, r0=6.0f, and L=0, r0=5.7f, respectively. This is in accord with a predominant D13 ground state and predominant S13 second excited state configuration for N14. For the transition to the 0+, T=1 first excited state, L=0 and r0=5.7f. Butler's stripping theory for the (He3, d) reaction with lp=1 and r0=5.8f accounts reasonably well for the C12(He3, d)N13 angular distribution. © 1960 The American Physical Society.
