Recent results from the deuteron charge-exchange on hydrogen programme at ANKE/COSY

A good understanding of the Nucleon-Nucleon interaction (NN) remains one of the most important goals of nuclear and hadronic physics. Apart from their intrinsic importance for the study of nuclear forces, NN data are necessary ingredients in the m odelling of meson production and other nuclear reactions at intermediate energies. Experiments at COSY, using a polarised deuteron beam and/or target, can lead to significant improvements in the np database by studying the quasi-free reaction on the neutr on in the deuteron - dp -> {pp}n. At low excitation energies of the final pp system, typically Epp {pp} (0)
