Recently, the LUNA collaboration has carried out a high precision measurement on the 3He(α, γ)7Be reaction cross section with both activation and online γ-detection methods at unprecedented low energies. In this paper the results obtained with the activation method are summarized. The results are compared with previous activation experiments, and the zero energy extrapolated astrophysical S factor is determined using different theoretical models.

Abstract
Recently, the LUNA collaboration has carried out a high precision measurement on the 3He(α, γ)7Be reaction cross section with both activation and online γ-detection methods at unprecedented low energies. In this paper the results obtained with the activation method are summarized. The results are compared with previous activation experiments, and the zero energy extrapolated astrophysical S factor is determined using different theoretical models.
