抜粋

The high-lying levels of 12B have been studied via the 9Be(α, p)12B reaction using 65 MeV α-particles. The reaction protons were analyzed with a quadrupole-dipole-dipole spectrograph, yielding a resolution of about 40 keV. Angular distributions were measured for 20 states ranging in excitation energy from 7.55 to 13.31 MeV. Results of DWBA calculations were compared to the angular distributions to attempt to set limits on the angular momentum transfers. The states seen at excitation energies of 10.57 and 13.31 MeV have potential significance to models of primordial nucleosynthesis via their possible importance to the 8Li(α, n)11B and 9Be(t, p)11B reactions respectively. A new reaction rate for the latter reaction was obtained.
