Electronic and vibrationalstate-selective differential cross sections are presented forprojectile energies of 0.1, 1.0 and 10.0,eV/u in the H$_{2}$orientation angles of 45$^circ$ and 89$^{circ}$. The electronicand the vibrational state-selective differential cross sections showsimilar behaviours: they decrease as the scattering angle increases,and beyond a specific angle the oscillating structures appear.Moreover, it is also found that the vibrational state-selectivedifferential cross sections are strongly orientation-dependent,which provides a possibility to determine the orientations ofmolecule H$_{2}$ by identifying the vibrational state-selectivedifferential scattering processes.
