Abstract

The differential cross sections for reactions ⁸He(p, d) ⁷He_g.s and ⁸He(p, t)⁶He₂₊ were measured by the coincidence of d + ⁶ He and t + ⁴He in a wide angular range from 15 to 130 degree in the center-of-mass system. The cross sections of the ⁸He(p, t)⁶He_g.s reaction were extremely lower than that of ⁸He(p, t)⁶He 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 (1p₃/₂) ²(1p_1/2)² may have some probability in the ground state wave function of ⁸He. The cluster structure of ⁸He = ⁵H + ³H could not be neglected.
