Abstract: The excitation function of the 8Li(d, t)7Li reaction was directly measured using 8Li beam irradiating a deuterated polyethylene target at center-of-mass system beam energies () between 0.3 and 1.2 MeV. This is the first cross section measurement of the above reaction below , covering Gamow peaks for of astrophysical interest. A broad resonance-like structure was observed at around . The astrophysical reaction rate deduced from the present result is far larger than the previously reported values estimated from extrapolation of data observed at higher energies, roughly by one order of magnitude at about .

Abstract: The excitation function of the 8Li()11B reaction was measured while identifying the final state event by event in the region of using a highly efficient detector system and a low-energy 8Li beam. The results are much improved both in statistics and precisions, and show smaller cross sections than those of previous measurements. A resonance-like structure is found at around .

Abstract: The 16O + 12C elastic scattering data have been well described, for the first time, with a shallow folded potential obtained from a single folding method. The constituent parameters of the potential, excepting one, for its real part are generated from the nucleon–16O and α–16O potentials, and the cluster structure of 12C. Only the repulsive part of the α–16O potential needs some adjustment to fit the data, reflecting the need to include the Pauli exclusion effects among the unclustered nucleons.

We discuss recent results of E.B. Norman et al. [Phys. Lett. B 519 (2001) 15] in relation to our earlier work [A. Ray et al., Phys. Lett. B 455 (1999) 69] and point out that the apparent disagreement between the two sets of experimental results is most likely due to the choice of different reference samples with which the comparisons have been done. In addition, the irradiation by heavy ion beam might also damage the lattice structure of the medium and such effect was not included in our calculations. We think that our earlier conclusion regarding the downward revision of predicted 8B solar neutrino flux by ≈2% should stand. [Copyright &y& Elsevier]
