Ms. Hussein et al., REAL PART OF THE POLARIZATION POTENTIAL FOR LI-11-INDUCED FUSION REACTIONS, Physical review. C. Nuclear physics, 47(5), 1993, pp. 2398-2400
We calculate the real part of the two-neutron-removal polarization pot
ential for the case of Li-11+Pb-208 collisions at energies near and be
low the Coulomb barrier. The real part of V(pol) is shown to be predom
inantly repulsive and to reduce the fusion cross section at above barr
ier energies. Below the barrier this potential changes sign and thus e
nhances the fusion cross section. However, this effect is considerably
weaker than the hindrance produced by the imaginary part of this pote
ntial.
