Description
We evaluate photoelectron angular anisotropy β parameters for the process of sequential two-photon double electron ionization of helium within the lowest-order time-independent perturbation theory. Our results indicate that for photoelectron energies outside the interval (Eslow,Efast), where Eslow=ω−VHe+ and Efast=ω−VHe, there is a considerable deviation from the dipole angular distribution, thus indicating the effect of electron correlation.
