Evaluation of Modern He(α, γ)Be Data
نویسندگان
چکیده
In both the Sun and the early universe, the He(α,γ)Be reaction plays a key role. The rate of this reaction is the least certain nuclear input needed to calculate both the primordial Li abundance in big bang nucleosynthesis (BBN) and the solar neutrino flux. Taking advantage of several recent highly precise experiments, we analyse modern He(α,γ)Be data using a robust and minimally model dependent approach capable of handling discrepant data sets dominated by systematic rather than statistical errors. We find S34(0) = 0.580 ± 0.043(0.054) keV b at the 68.3(95.4)% confidence level.

J un 1 99 3 1 Alpha scattering and capture reactions in the A = 7 system at low energies
Differential cross sections for 3 He-α scattering were measured in the energy range up to 3 MeV. These data together with other available experimental results for 3 He +α and 3 H +α scattering were analyzed in the framework of the optical model using double-folded potentials. The optical potentials obtained were used to calculate the astrophysical S-factors of the capture reactions 3 He(α, γ) 7...

The possibility of employing α-Al2O3:C (TLD-500) for estimation of gamma dose in mixed n-γ radiation fields by two peak method has investigated. It was found that the main peak can be reliably deconvoluted to two component glow peaks. The ratio of peak 2 to peak 1 in pure gamma ray radiation field (137Cs) is 1.49 whereas irradiation by Am-Be neutrons results in a ratio of 1.12. The precision of...

متن کاملPreliminary measurement of the He(α,γ)Be cross section
The current uncertainty of the He(α,γ)Be cross section greatly hinders the understanding of the high-energy solar neutrino flux from the Be(p,γ)B reaction and, thus, is significantly important in the verification of the Standard Solar Model. I present the results of my efforts this summer in assisting the group lead by Kurt Snover to prepare for a high-precision measurement of the He(α,γ)Be cro...
متن کاملIncreasing vitamin E content of canola (Brassica napus L.) by transferring γ-tmt gene
Vitamin E is one of the lipid soluble vitamins consisting of several isoforms, including tocopherols and tocotrienols amongst which the alpha tocopherol is the most active one. The conversion of γ tocophrol to α tocopherol takes place by the activity of γ-tmt enzyme. Many plants including canola lack the γ-tmt gene to enable them to convert γ tocophrol into α tocopherol. The aim of this study w...
