Experimental elastic scattering cross sections of 6He ions by 58Ni and 209Bi nuclei at 10 МеV and 14.7, 16.2, 17.8, 19.1, 22 МеV, respectively, are analyzed in the framework of optical model with electric optical potential using. This potential allows to take into account the polarizability and breakup of 6He projectile in the field of target nucleus in the effective way. The considerable influence of projectile breakup on elastic scattering cross sections formation near the Coulomb barrier is shown. The last fact is the direct evidence of dineutron configuration existence in the ground state in this exotic nucleus.
Verbitsky et al. (Sat,) studied this question.
