We present a practical S-matrix to potential inversion procedure for coupled-channel scattering. The inversion technique developed is applied to non-diagonal S J ll ′ for spin one projectiles, yielding a tensor interaction T R and is also applicable to spin-1 2 plus spin-1 2 scattering. The method is a generalization of the iterative-perturbative, IP, method. It is tested and evaluated and we i...

Data for the scattering of 6 He, 8 He, 9 Li, and 11 Li from hydrogen are analyzed within a fully microscopic folding model of proton-nucleus scattering. Current data suggest that of these only 11 Li has a noticeable halo. The available data for the 6 Li(γ, π +) 6 He gs reaction support the conclusion that 6 He does not.

The nucleon-deuteron analyzing power A y in elastic nucleon-deuteron scattering poses a longstanding puzzle. At energies E lab below approximately 30 MeV A y cannot be described by any realistic NN force. The inclusion of existing three-nucleon forces does not improve the situation. Because of recent questions about the 3 P J NN phases, we examine whether reasonable changes in the NN force can ...

We discuss a recent computation of Compton scattering on the deuteron at photon energies of order the pion mass. An interaction kernel is computed in baryon chiral perturbation theory and sewn to phenomenological deuteron wave functions. As an appetizer, we consider a computation of the pion-deuteron scattering length using this method.
