Query: Gamow Functionals on Operator Algebras   We obtain the precise form of two Gamow functionals, representing the
exponentially decaying part of a quantum resonance and its mirror image that
grows exponentially, as a linear, positive and continuous functional on an
algebra containing observables. These functionals do not admit normalization
and, with an appropiate choice of the algebra, are time reversal of each other.
