Pönisch, Volker (1986) Subbarrier fusion of the oxygen isotopes. Dissertation (Ph.D.), California Institute of Technology. http://resolver.caltech.edu/CaltechTHESIS:06302010-080153741
The subbarrier fusion process is studied for systems involving oxygen isotopes. A one-channel incoming wave boundary condition (IWBC) calculation gives an excellent fit to fusion cross section data for ^(16)O + ^(16)O. An IWBC coupled channels calculation for ^(17)O + ^(16)O that includes inelastic excitations as well as one-neutron transfer with formfactors calculated in a consistent single-particle framework reproduces the subbarrier enhancement down to four fifths the barrier height, but not below that. The calculation does not invoke the adiabatic approximation, which would create non-unitarity in the coupled channels equations. The measured subbarrier fusion cross section for ^(18)O + ^(16)O is well reproduced by an IWBC coupled channels calculation with two-neutron transfer, but the calculation disagrees with the above-barrier data.
