Elastic α-C12 Scattering and the C12(α,γ)O16 E2 S Factor
Angular distributions of 12C(α,α)12C have been measured for Eα=2.6–8.2 MeV, at angles from 24° to 166°, yielding 12 864 data points. R-matrix analysis of the ratios of elastic scattering yields a reduced width amplitude of γ12=0.47±0.06 MeV1/2 for the Ex=6.917 MeV(2+) state in 16O(a=5.5 fm). The dep...

R-matrix analysis of the ratios of elastic scattering yields a reduced width amplitude of γ12=0.47±0.06 MeV1/2 for the Ex=6.917 MeV(2+) state in 16O(a=5.5 fm). The dependence of the χ2 surface on the interaction radius a has been investigated and a deep minimum is found at a=5.42-0.27+0.16 fm. Using this value of γ12, radiative α capture and 16N β-delayed α-decay data, the S factor is calculated at Ec.m.=300 keV to be SE2(300)=53-18+13 keV b for destructive interference between the subthreshold resonance tail and the ground state E2 direct capture. | ||

Elastic α-C12 Scattering and the C12(α,γ)O16 E2 S Factor |
| abstract |
Angular distributions of 12C(α,α)12C have been measured for Eα=2.6–8.2 MeV, at angles from 24° to 166°, yielding 12 864 data points. R-matrix analysis of the ratios of elastic scattering yields a reduced width amplitude of γ12=0.47±0.06 MeV1/2 for the Ex=6.917 MeV(2+) state in 16O(a=5.5 fm). The dependence of the χ2 surface on the interaction radius a has been investigated and a deep minimum is found at a=5.42-0.27+0.16 fm. Using this value of γ12, radiative α capture and 16N β-delayed α-decay data, the S factor is calculated at Ec.m.=300 keV to be SE2(300)=53-18+13 keV b for destructive interference between the subthreshold resonance tail and the ground state E2 direct capture. |
