摘要: The +2n and t+t clustering of the 6He ground state were investigated by means transfer reaction 6He(p,t)4He at 25 MeV/nucleon. experiment was performed in inverse kinematics GANIL with SPEG spectrometer coupled to MUST array. Experimental data for analyzed a distorted wave Born approximation (DWBA) calculation, including two neutrons triton transfer. couplings 6He4He+2n breakup channels taken into account polarization potential deduced from coupled-discretized-continuum analysis 6He+1H elastic scattering measured same time. influence on calculations +t exit sequential is discussed. final calculation gives spectroscopic factor close one configuration as expected. obtained much smaller than theoretical predictions.
