  • 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.

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.
