The photoionization cross sections and asymmetry parameters of the three main valence ionization processes in HI, corresponding to the formation of, respectively, 6a, l l u , and 10 (T holes, were calculated in the random-phase approximation (RPA). Our particular computational procedure, based on so

Total photoionization, cross sections for H2 are ulculared in the random phase approximation (RPA) through a nur;lerical analytic coniinuation procedure applied to the polarrability for complex val&s of the frequency. The reprcsentition of the polarizability that is required is obtained from 3 discr
## Abstract Within the framework of the complex basis function method, the photoionization cross sections of H and H~2~ were calculated based on the variational principle for the frequencyโdependent polarizabilities. In these calculations, complex orbital exponents of Gaussianโtype basis functions
