Abstract :
Generalized cross sections 
and 
for the two-photon ionization of He from the metastable 
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 
and 
p intermediate states. The ratio / shows a minima at the wavelengths close to 3743 and 4450 Å.
