Abstract：
Angular distribution for (α,t), (α,d) and (α,p) reactions of α particle on nuclei ^10,11B at 31.2 MeV incident energy have been measured by particle identification system. The shapes of the outgoing particle angular distribution show that the cross sections in backward angular region have different enhacement in ¹¹B(α,t₀)×¹²C_g﹒s, ¹¹B(α,d₀)¹³C_g﹒s, ¹⁰B(α,d₀)¹²C_g﹒s, ¹⁰B(α,d₁)¹²C_1st, ¹¹B(α,p₀)¹⁴C_g﹒s. and the isotopic effect of the backward angle anomaly in the reac tions (α,t₀) and (α,p₀) is just opposed to that of (α, α) elastic scattering from nucleus B.
Finally, the reaction mechanism is discussed qualitatively in terms of the Dispersion Theory of direct nuclear reaction. The calculation of the singularity position of the (α,t), (α,d) and (α,p) reactions on nuclei ^10,11B is performed using the Feynman Graphs. The initial conclusion is the following:
The principal mechanism is direct stripping in the for-ward angle region and heavy particle stripping in the backward angle region.
For the raction ¹¹B(α,d₀)¹³C_g﹒s. however, there is a multimechanism superposition in the backward angle region.
