Abstract

The breakup cross sections in the reaction 6^6He+12^{12}C are calculated at about 40 MeV/nucleon using the high-energy approximation (HEA) and with the help of microscopic optical potentials (OP) of interaction with the target nucleus 12^{12}C of the projectile nucleus fragments 4^4He and 2n. Considering the di-neutron hh=2n as a single particle the relative motion hαh\alpha wave function is estimated so that to explain both the separation energy of hh in 6^6He and the rms radius of the latter. The stripping and absorbtion total cross sections are calculated and their sum is compared with the total reaction cross section obtained within a double-folding microscopic OP for the 6^6He+12^{12}C scattering. It is concluded that the breakup cross sections contribute in about 50% of the total reaction cross section.
