N2 - We present an experimental investigation into the angular and energy distributions of electrons set free by the interaction of hydrogen molecular ions with strong laser fields. The results extend on those presented previously [M. Odenweller, Phys. Rev. Lett. 107, 143004 (2011)PRLTAO0031-900710.1103/ PhysRevLett.107.143004] for circularly polarized light. Pulses of laser light (λ=780 nm, I≈6×1014 W cm-2, τ≈40 fs) of both linear and circular polarization are focused onto an H2+ molecular ion beam. The momenta of the proton and electron fragments are determined in a coincidence experiment, enabling electron momentum emission patterns in the molecular frame to be deduced for specific values of internuclear distances.
