On the quantum mechanical treatment of decaying non-relativistic systems

  • 25 Accesses

  • 6 Citations


The usual treatment of decaying non-relativistic particles by means of a non-unitary irreducible representation of the Galilei group is deduced from a suitable formulation of symmetry principles. In such a formulation time translation is distinguished from time evolution; this point is crucial to obtain the irreversible behaviour of unstable particles.
