TL;DR
This paper summarizes high-precision activation measurements of the 3He(alpha,gamma)7Be reaction at low energies, compares them with previous data, and evaluates theoretical models to determine the astrophysical S factor.
Contribution
It provides a comprehensive comparison of recent LUNA activation results with earlier measurements and assesses theoretical models for zero-energy extrapolation.
Findings
LUNA results are consistent with previous measurements.
The zero-energy S factor is determined with improved precision.
Theoretical models show varying agreement with experimental data.
Abstract
Recently, the LUNA collaboration has carried out a high precision measurement on the 3He(alpha,gamma)7Be reaction cross section with both activation and on-line gamma-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.
