Coupled channels treatment of transfer reactions

Consistent coupled channels calculations, using folded optical potentials, are performed by iteration for the reactions ¹⁶O(d, d), ¹⁶O(d, p), and ¹⁷O(p, p). The kernel is greatly changes when the nonorthogonality of the channel wave functions is included. The non-orthogonality corrections tend to cancel the effects from higher-order processes except for ¹⁷O(p, p) where only higher-order processes are important. The use of folded potentials reduces both effects.
