Abstract

The cross section of the C14(d, p)C15* reaction (Q=1.76 MeV) to the first excited state of C15 at 0.75 MeV was measured for deuteron energies between 2.7 and 3.4 MeV. The cross section was obtained from the yield of the γ ray to the C15 ground state. The energy of this γ ray was measured to be 0.750±0.007 MeV. The γ-ray angular distribution relative to the deuteron beam was measured at five deuteron energies between 2.9 and 3.4 MeV. The presence of a P4(cosθ) term in the distributions together with previous work establishes the C15 0.75-MeV level as 52+. The measured angular distributions were found to be in agreement with predictions based on stripping theory. The cross section for the Li7(d, p)Li8* reaction (Q=1.17 MeV) to the first excited state of Li8 at 0.98 MeV was measured for deuteron energies between 1.9 and 3.3 MeV. The cross section was obtained from the yield of the γ ray to the Li8 ground state. The γ-ray energy was measured to be 0.980±0.010 MeV. The anisotropy of this γ ray was measured at 23 deuteron energies between 1.9 and 3.3 MeV. These results were also consistent with the predictions of stripping theory if assignments of 1+ for the Li8 0.98-MeV level and M1 for the 0.98-MeV γ ray are assumed.
