    "abstract": "The 2H(p,n) charge exchange reaction at T_p=790 MeV is used to study the\nDelta(1232)-nucleon interaction in the Delta resonance excitation energy\nregion. For the Delta-N potential, a meson exchange model is adopted where pi,\nrho, omega, and sigma meson exchanges are taken into account. The deuteron\ndisintegration below and above pion threshold is calculated using a coupled\nchannel approach. Various observables, such as the inclusive cross section, the\nquasifree Delta decay, the coherent pion production, and the two-nucleon\nbreakup are considered. It is shown that these observables are influenced by\nthe dynamical treatment of the Delta degrees of freedom. Of special interest is\nthe coherent pion decay of the Delta resonance which is studied by means of the\nexclusive reaction 2H(p,n pi+)2H. Both the peak energy and the magnitude of the\ncoherent pion production cross section depend very sensitively on the strength\nof the Delta-N potential. The coherent pions have a peak energy of 300 MeV and\na strongly forward peaked angular distribution.",
