Abstract
We consider the survival amplitudeA(t) for a normalized decaying state whose energy spectral density vanishes asymptotically as an inverse power. By using simple calculus a Taylor expansion ofA(t) is derived aroundt=0, the form of the remainder term identified, and a physical significance given to the other coefficients. It is shown that the Taylor remainder may contain logarithms oft besides powers.
