Synopsis We use a circularly polarized attosecond pulse train (APT) together with a weak replica of the fundamental circularly polarized infra-red (IR) field to reconstruct the ionization phase of the dipole allowed (2s2p) 1 P° resonance in atomic helium by analyzing the momentum distribution of the ionized photoelectrons within the polarization plane.
