    "abstract": "The strong-field approximation can be and has been applied in both length\ngauge and velocity gauge with quantitatively conflicting answers. For\nionization of negative ions with a ground state of odd parity, the predictions\nof the two gauges differ qualitatively: in the envelope of the angular-resolved\nenergy spectrum, dips in one gauge correspond to humps in the other. We show\nthat the length-gauge SFA matches the exact numerical solution of the\ntime-dependent Schr\\\"odinger equation.",
