The reaction 3 H(α,γ) 7 Li has been investigated for E CM = 79–464 KeV with the use of Ge(Li) detectors. The astrophysical S ( E ) factor is found to be energy-dependent, rising smoothly to S (0) = 0.14±0.02 keV b at zero energy. This is a facto

The energy levels of 26Al between Ex = 6.3 and 6.5 MeV, corresponding to proton threshold energies in the 25Mg + p reaction from E p = 0 to 200 keV , have been investigated using the reactions 27 Al(su3 He, α)26Al and 24Mg(3He, p)26Al. Despite early

The polarization P y for the 3 H(p, n) 3 He reaction was measured for energies between 2 and 4 MeV. Special care was given to minimizing the effects of background and to interpreting the experimental spectra. The new values for P y are significantly

Analyzing powers for these charge symmetric reactions were measured at low energies where symmetry breaking effects due to the Coulomb interaction should be enhanced. Differences in the magnitudes exist and must be explained if charge symmetry holds;
