Synopsis

In a previous paper (to be quoted as (I)) angular distribution measurements have been described of four proton groups from the B(d, p)B reaction at a deuteron energy of Ed = 0.31 MeV. In the present investigation measurements were added at Ed = 0.20, 0.45 and 0.60 MeV.

The differential cross section at ϑ = 120° has also been determined as a function of deuteron energy (Ed = 0.175–0.700 MeV) by means of a proton scintillation spectrometer. The relative intensities of the four proton groups show irregularities at Ed = 0.21 MeV corresponding to a new C resonance level at an excitation energy of 26.93 MeV.

Angular distributions have been analyzed into a stripping contribution and a contribution from compound nucleus formation. It is shown that the stripping contribution is large for at least two of the four proton groups down to the lowest deuteron energies. The values found by Butler analysis for the angular momentum transfer ln are in agreement with known spins and parities.
