✦ Synopsis

Although the one-body dissipation mechanism has been successfully applied to the description of nuclear reactions, recent calculations suggest that quantum localization should completely suppress this dissipation mechanism. The particle evaporation process was not taken into account in those calculations. We show, through Fermi accelerator simulations, that this mechanism is a source of decoherence in the quantum dynamics of the system. This leads to a strong hindrance of quantum localization, and, as a consequence, to dissipation of collective energy.
