Abstract
The spin structure of the q-qBAR potential is studied by evaluating fi ne and hyperfine meson mass splittings. We consider a potential derive d from a model of the non-perturbative gluon propagator and compare it s prediction with other approaches. We conclude that the long-distance part of the potential cannot be a pure scalar and that a vector-scala r mixture is favoured.
