Phys. Rev. A 55, 1550–1551 (1997)Comment on ``Saddle-point ionization and the Runge-Lenz invariant''Received 18 August 1995; published in the issue dated February 1997 Arguments made recently by Howard [Phys. Rev. A 51, 3934 (1995)] as to (i) the consequences of the nonexistence of an effective potential in the problem of a hydrogen atom in a circularly polarized microwave field, and (ii) the claimed advantages of his stability analysis as compared to methods based on harmonic expansion at an equilibrium point are examined. © 1996 The American Physical Society URL:
