A two-source model is used in this paper to describe the reaction process of Em(8B, p7Be)Em at 1.2A GeV. The distribution of azimuthal angle between 7Be and p, the transverse momentum distribution of p, and the total transverse momentum distribution of 7Be and p produced in the reactions are analyzed. It is found that the modelling results describe approximately the fluctuation and mean trend of the experimental data of Stanoeva {et al}.
