Estimation of the breakup cross sections in 6He+12C reaction within high-energy approximation and microscopic optical potential
Abstract
The breakup cross sections in the reaction 6He+12C 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 12C of the projectile nucleus fragments 4He and 2n. Considering the di-neutron h=2n as a single particle the relative motion hα wave function is estimated so that to explain both the separation energy of h in 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 6He+12C scattering. It is concluded that the breakup cross sections contribute in about 50% of the total reaction cross section.
