    "abstract": "We find conditions required to achieve complete population transfer, via\ncoherent population trapping, from an initial state to a designated final state\nat a designated time in a degenerate $n$-state atom, where transitions are\ncaused by an external interaction. In systems with degenerate states there is\nno time ordering. Analytic expressions have been found for transition\nprobabilities in a degenerate $n$-state atom interacting with a strong external\nfield that gives a common time dependence to all of the transition matrix\nelements. Except for solving a simple $n^{th}$ order equation to determine\neigenvalues of dressed states, the method is entirely analytic. These\nexpressions may be used to control electron populations in degenerate $n$-state\natoms. Examples are given for $n=2$ and $n=3$.",
