摘要：

The decay of an unstable state is investigated for the Friedrichs model with a singular continuous spectrum. On the basis of a scaling approach, it is shown that the survival amplitude may exhibit the Mittag-Leffler relaxation. The validity of the scaling approach is investigated numerically as well.
