    "abstract": "We derive Gamow vectors from S-matrix poles of higher multiplicity in analogy\nto the Gamow vectors describing resonances from first-order poles. With these\nvectors we construct a density operator that describes resonances associated\nwith higher order poles that obey an exponential decay law. It turns out that\nthis operator formed by these higher order Gamow vectors has a unique\nstructure.",
