STUDIES OF Be⁹ (d,p), (d,t) AND (d,α) REACTIONS

Abstract

The reactions of Be9(d, p0)Be10(0), Be9(d, p1)Be10(3.368 MeV), Be9(d, t0)Be8(0), Be9(d, α0)Li7(0) and Be9(d, α1) Li7 (0.478 MeV) have been studied at deuteron bombarding energies from 0.1 to 2.5 MeV. The angular distributions of these five groups of outgoing particles have been measured respectively between θL = 10°and 155°at eleven bombarding energies of 0.150, 0.220, 0.401, 0.706, 1.005, 1.301, 1.484, 1.750, 2.000, 2.250 and 2.500 MeV. The excitation functions of the Be9 (d,p0) Be10 reaction have been measured at θL = 135° from Ed = 0.1 to 2.5 MeV, at θL = 95° from Ed = 0.1 to 2.2 MeV and at θL = 112.5° from Ed, = 0.5 to 2.5 MeV, respectively. By use of thicker targets (100-300μg/cm2) and at Ed = 1.2 MeV, the absolute cross sections of the Be9(d, p0)Be10 reaction were measured at θL = 135°and 112.5°; the results obtained are: σ(p0)(θL = 135°)= 1.60 mb/st and σ(p0)(θL = 112.5°)=1.55 mb/st. Thus, the behaviours of the cross sections of all these five groups of outgoing particles have been obtained in this energy range. These experimental results are discussed to some extent.
