Abstract：
The new experimental data of ¹¹B(p,α₁)⁸Be^*(1)(2α) three-body decay show that the continuous α spectrum of the two alpha particles produced by the intermediate nuclear ⁸Be^*(1) looks like a saddle type distribution. To explain the experimental facts, we have written a Monte Carlo simulation program to the p+¹¹B reaction. The calculation results of the program indicate that the anisotropy distribution emission of the decay alpha particles produced by ⁸Be^*(1) can give a satisfying explanation to the experimental spectrum.
