dc.description.abstract | Spectra up to 25 MeV excitation in 16O have been obtained from 12C(6Li, d) at 42 MeV bombarding energy. Angular distributions have been measured for ten states, including two J[pi] = 1- states of astrophysical interest, and appear to be mostly direct [alpha]-transfer. In addition, data for 16(6Li, d)20Ne(g.s.) and 20Ne*(2+) have been obtained. Excitation energies and widths have been extracted for states in 16O, including several states at Ex > 15 MeV. Alpha spectroscopic factors, S[alpha], and reduced [alpha]-widths, [gamma]2[alpha] and [theta]2[alpha] have been deduced for levels in 16O and 20Ne and compared with theoretical predictions. The J[pi] = 1- levels in 16O at 7.12 and 9.6 MeV excitation appear to have comparable S[alpha] and [gamma]2[alpha] values, viz. [gamma]2[alpha] (7.12 MeV)/[gamma]2[alpha] (9.6 MeV) = 0.6+1.7-0.3. Both states have apparent S[alpha] and [gamma]2[alpha] values smaller than that for the J[pi] = 2+ "[alpha]-cluster" state at 6.9 MeV however. Furthermore, the observed line shape for the J[alpha] = 1-, 9.6 MeV level indicates [Gamma]c.m. = 400 +/- 50 keV, which is substantially less than the accepted width for this level [Gamma]c.m. = 510+/-60 keV). The possible implications of these results for stellar helium burning calculations are discussed. | en_US |
