摘要
Abstract
The D(d ,γ)4 He fusion reaction at low energy was studied in this paper .Due to the small yields ,the high energy and the strong background of γ‐ray ,a big NaI‐plastic scintillator anti‐Compton spectrometer was employed to increase the detect effi‐ciency and reduce the impact of the cosmic rays ,and the method of the time‐of‐flight (TOF) was used to discriminate neutron and gamma to reduce the background of neutron and cosmic rays .The thick and thin deuterium‐loaded titanium target experi‐ments were performed at Ed =300 keV .The background was subtracted by our fitting method .T he cross section is 2.47 × 10-37 m2 for the thick target and 4.36 × 10-37 m2 for the thin target .关键词
