Abstract
We report on calculations of the third-order optical harmonic coefficients for atomic hydrogen and helium, using -matrix expansions for the excited spectra. The results obtained are in excellent agreement with previous theoretical and experimental determinations. The method is readily applicable to the calculation of other multiphoton processes for other atomic systems.
