    "abstract": "The description of the three-nucleon system in terms of nucleon and $\\Delta$\ndegrees of freedom is extended to allow for explicit pion production\n(absorption) from single dynamic $\\Delta$ de-excitation (excitation) processes.\nThis mechanism yields an energy dependent effective three-body hamiltonean. The\nFaddeev equations for the trinucleon bound state are solved with a force model\nthat has already been tested in the two-nucleon system above pion-production\nthreshold. The binding energy and other bound state properties are calculated.\nThe contribution to the effective three-nucleon force arising from the pionic\ndegrees of freedom is evaluated. The validity of previous coupled-channel\ncalculations with explicit but stable $\\Delta$ isobar components in the\nwavefunction is studied.",
