Abstract
The short-time behaviour of the quantum survival probability is examin ed. The origin of previous discrepancies on the short-time behaviour i s explained by means of a discrete decomposition of the survival ampli tude into a sum of decaying exponential terms and w-functions. Several possible non-exponential dependences are described and exemplified.
