Abstract
A unified treatment of the total time regime of the decay of an unstable macroscopic state is derived by functional integral methods. A new one-variable integral representation for the conditional probability is obtained. Previous results with only a limited range of validity are contained as special cases. Further, the evolution of initial states in the vicinity of the instability point is studied.Keywords
