Subbarrier Fusion of the Oxygen Isotopes
Abstract
The subbarrier fusion process is studied for systems involving oxygen isotopes. A onechannel 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 oneneutron transfer with formfactors calculated in a consistent singleparticle 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 nonunitarity 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 twoneutron transfer, but the calculation disagrees with the abovebarrier data.
