Photoelectron momentum distributions of Ne₂ in the molecular frame for the circularly polarized light. a, d are simulated spectra with two coherently superimposed atomic distributions; b, e – measured for the direct and indirect dissociations, respectively; c, f are the same as the distributions in b, e but normalized to the monomer distribution in order to remove ionization weighting of the final momenta. The red side of the sketched molecule defines the momentum direction of the measured neon ion. k_║ and k_⊥ are the electron momentum components parallel and perpendicular to the dimer axis, respectively
