Atomic Hydrogen in Strong Converging Laser Field of Circular Polarization

We first proved that the modified potential of atomic hydrogen in the converging laser field of circular polarization is an exact uniform field in the range of r ≤ R₀(∝ I^1/2ω^-2), but Coulomb potential in the range of r > R₀. Then the energy levels shallow and split, the wavefunction undergoes distortion.
