The cross section of the d + 3He → α + p fusion reaction has been determined with regard to its systematic variation with energy (ECM) based on the available experimental data. Information is provided on the angular distribution dσ/dΩ(θp, E) at energies up to ECM = 8.0 MeV and the total cross section σ(ECM) for the range ECM = 3.0–8.0 MeV. The relevance of the presented results for fusion plasmas heated with RF heating of 3He minority in D and DT plasmas is discussed.
