Description

The cross section for the radiative capture 3He(4He, γ)7Be has been measured 525 keV in the centre-of-mass by detection of prompt capture γ-rays. The targets were 3He-implanted Nb foils that allowed us to circumvent the experimental difficulties inherent in the use of extended gas cells for absolute measurements. The results give an inferred zero-energy cross-section factor of S34(0) = 0.47 +- 0.04 keVxb. The present result is compared with results from previous capture γ-ray yield and 7Be-activity methods of measuring the cross-section factor. (orig.)
