The present work presents the momentum distribution of helium ions, created in the single ionization of helium by a 5.9 fs, CEO phase stabilized laser pulse with a small ellipticity. The difference from the expected momentum distribution created by circular light is explained using the ADK theory and classical propagation of the particles in the electric field of the laser.
