Abstract

A blow-in type windowless thick He gas target has been developed to measure ⁴He(¹²C,¹⁶O) γ cross section for astrophysical interests. We use a ¹²C beam of energy from 6 to 2.8 MeV and detect ¹⁶O recoils at forward angles. Numerous ¹²C backgrounds have been rejected by particle identification techniques. ¹⁶O backgrounds from the target are not many but fatally harmful. Our techniques to reduce the ¹⁶O backgrounds are described.
