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