^1^2C(^6Li, d)^1^6O at E(Li) = 90 MeV
The ^1^2C(^6Li, d)^1^6O reaction has been studied at E(^6Li) = 90.2 MeV with a magnetic spectrometer. Spectra up to E"x ~ 30 MeV in ^1^6O have been obtained and decay line widths, Γ"c"."m"., have been extracted for broad levels. Known α-cluster states (J^π = 2^+, E"x =...

^1^2C(^6Li, d)^1^6O at E(Li) = 90 MeV |
| abstract |
The ^1^2C(^6Li, d)^1^6O reaction has been studied at E(^6Li) = 90.2 MeV with a magnetic spectrometer. Spectra up to E"x ~ 30 MeV in ^1^6O have been obtained and decay line widths, Γ"c"."m"., have been extracted for broad levels. Known α-cluster states (J^π = 2^+, E"x = 6.9 MeV; J^π = 4^+, E"x = 10.35 MeV) are preferentially populated exhibit sharply forward peaked angular distributions in contrast with (^6Li, d) data obtained at lower bombarding energies. These features are well reproduced by reaction calculations assuming direct alpha-particle transfer provided one utilizes realistic optical model, target, and projectile wave functions. Alpha spectroscopic factors and reduced alpha widths have been extracted for levels E"x < 12 MeV including J^π = 1^- levels of astrophysical interest. The results are compared with other recent measurements and theoretical calculations. There is generally at least qualitative agreement (within x 2) between the various experiments and theories. The analysis indicates a non-negligible alpha width for the J^π = 1^- level at E"x = 7.1 MeV in ^1^6O (which determines the ^1^2C -> ^1^6O stellar helium burning rate) with 0.3 < θ"α^2 (7.1 MeV)/θ"α^2 (9.6MeV) < 0.6 and 0.1 < θ"α^2 (7.1 MeV)/ θ"α^2 (6.9 MeV) < 0.4. |
