    "abstract": "Resonance trapping appears in open many-particle quantum systems at high\nlevel density when the coupling to the continuum of decay channels reaches a\ncritical strength. Here a reorganization of the system takes place and a\nseparation of different time scales appears. We investigate it under the\ninfluence of additional weakly coupled channels as well as by taking into\naccount the real part of the coupling term between system and continuum. We\nobserve a saturation of the mean width of the trapped states. Also the decay\nrates saturate as a function of the coupling strength. The mechanism of the\nsaturation is studied in detail. In any case, the critical region of\nreorganization is enlarged. When the transmission coefficients for the\ndifferent channels are different, the width distribution is broadened as\ncompared to a chi_K^2 distribution where K is the number of channels. Resonance\ntrapping takes place before the broad state overlaps regions beyond the\nextension of the spectrum of the closed system.",
