Strong Orientation Effects in Ionization of H$_2^+$ by Short, Intense,   High-Frequency Light Sources
  We present three dimensional time-dependent calculations of ionization of arbitrarily spatially oriented H$_2^+$ by attosecond, intense, high-frequency laser fields. The ionization probability shows a strong dependence on both the internuclear distance and the relative orientation between the laser field and the internuclear axis.
