-The above formula was found to be quite adequate in
describing sub-barrier elastic scattering of heavy ions. For
strongly deformed nuclei the inclusion of the low lying 2 4
state in evaluating V results in a almost purely absorptive
polarization potential. The correction AO due to the real
component is quite negligible. Using V' of Eq. (17), then
results in
