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

Abstract

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.
