RT info:eu-repo/semantics/article T1 A discussion on the properties of Gamow states A1 Gadella Urquiza, Manuel K1 Quantum resonance K1 Resonancia cuántica AB Gamow states are vector states for the pure decaying part of a quantumresonance. We review and analyze the properties of Gamow vectors in different representations. In particular, we discuss the controversial problem of assigning a meanvalue of the energy for a Gamow state from several points of view. The question onwhether a Gamow state is a pure state or not is also analyzed here, as has relevanceon the assignation of a non-zero value for the entropy for a Gamow state.
