Abstract :
Generalized cross sections \\hat{\\sigma }_{L} and \\hat{\\sigma }_{C} for the two-photon ionization of He from the metastable 2^{1}S state are calculated for linearly and circularly polarized incident laser light, respectively, in the wavelength range 3725-5100 Å. Significant enhancement of cross sections occurs through real 3^{1}P and 4^{1}P p intermediate states. The ratio \\hat{\\sigma }_{C} / \\hat{\\sigma }_{L} shows a minima at the wavelengths close to 3743 and 4450 Å.
