Abstract: We study the relaxation of a degenerate two-level system interacting with a heat bath, assuming a random-matrix model for the system-bath interaction. For times larger than the duration of a collision and smaller than the PoincarĂ© recurrence time, the survival probability of still finding the system at timet in the same state in which it was prepared att=0 is exactly calculated.
