Proton capture to bound and unbound states of C12

Published

Journal Article

The cross section for the B11(p,)C12 reaction leading to the 19 MeV region of C12 has been measured at lab=60°for Ep of 23 to 60 MeV. Angular distributions of cross sections and analyzing powers were measured at Ep=28.7 MeV. The B11(p,0,1)C12 cross sections were measured at lab=60°for Ep of 8 to 60 MeV, with angular distribution measurements at Ep of 14.5, 17.0, and 28.7 MeV. The results are compared to direct capture calculations which, in the case of transitions to the 19 MeV region, treat the final state as both a bound and unbound state. The procedures for calculating direct capture to unbound final states are described. The possible existence of a giant resonance state is discussed.
