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