摘要：

The differential cross sections for reactions He-8(p, d)He-7(g.s) and He-8(p, t)He-6(2+) were measured by the coincidence of d + He-6 and t + He-4 in a wide angular range from 15 to 130 degree in the center-of-mass system. The cross sections of the He-8(p, t)He-6(g.s.) reaction were extremely lower than that of He-8(p, t)He-6(2+) reaction, and was not obtained from the present data. The experimental results were compared to the preliminary theoretical calculations in the frame of adiabatic distorted-wave approximation with the code Fresco. The results show that the configuration of (1p(3/2))(2)(1p(1/2))(2) may have some probability in the ground state wave function of He-8. The cluster structure of He-8 = H-5 + H-3 could not be neglected.
