    "abstract": "Klauder\u0027s recent generalization of the harmonic oscillator coherent states\n[J. Phys. A 29, L293 (1996)] is applicable only in non-degenerate systems,\nrequiring some additional structure if applied to systems with degeneracies.\nThe author suggests how this structure could be added, and applies the complete\nmethod to the hydrogen atom problem. To illustrate how a certain degree of\nfreedom in the construction may be exercised, states are constructed which are\ninitially localized and evolve semi-classically, and whose long time evolution\nexhibits \"fractional revivals.\"",
