【 摘 要 】

We report the angular distribution of the fragment ions formed in the collision of Xe9+ions with isolated water molecules. A significant anisotropy, and strong alignment effects have been seen. It is observed that there is a strong forward - backward asymmetry in the emission of protons and oxygen ions in the three body dissociation of multiply charged water molecules.
