Pick-up Reactions on a9Be Target

Abstract

Absolute differential cross sections have been measured for the 9Be(p,d)8Be(0) and 9Be(p,p)9Be(0) `reactions at incident proton energies of 4.85 and 5.49Mev, and for the 9Be(d,t)8Be reaction at 5.86Mev; the pick-up reactions have been analysed in terms of the Butler theory. A comparison of the (p,d) results with those at higher proton energies gives the ranges of validity of the Butler theory and the `transparent-nucleus' Born approximation pick-up theory for the reaction; the neutron reduced width is also deduced from these results. A comparison of the (d,t) results with those at higher deuteron energies shows consistency over a wide energy range: a comparison with the (p,d) reaction gives the triton form-factor|A0|2N12. Excitation functions have been measured for the reaction products of 9Be+p for bombarding energies between 3.5 Mev and 6.0 Mev and for the reaction products of 9Be+d for bombarding energies between 3.8 Mev and 6.3 Mev.
