摘要：

The astrophysically important He-3(alpha, gamma)Be-7 reaction was studied at high energies where the available experimental data are in contradiction. A thin window He-3 gas cell was used and the cross section was measured with the activation method. The obtained cross sections at energies between E-c.m. = 1.5 and 2.5 MeV are compared with the available data and theoretical calculations. The present results support the validity of the high energy cross section energy dependence observed by recent experiments. (c) 2013 Elsevier B.V. All rights reserved.
