Abstract
The ratio μN of the cross section for circularly polarized light to that for linearly polarized is numerically investigated for N-photon ionization of atomic hydrogen. For N<4, it appears that the gain factor is greater than unity. For N≥4, the ratio μN is generally smaller than unity and decreases when the multiphoton order N increases.
