Ion transfers
Web@see Fig. 1~a!#, where an excited ion transfers its energy to a nearby ion in the ground state. This results in diffusion of the excitation, and finally loss of the excitation if one of the Er31 ions couples to a defect, for example, a hydroxyl group.5,6 Under conditions of amplification, most of the ions are ex- WebSECONDARY ION TRANSFER 5. Secondary Ion Transfer. After the secondary ions have been extracted from the sample surface by the immersion lens they are transferred by a second electrostatic (transfer) lens into the mass spectrometer. The purpose of this transfer lens is to form a real magnified image of the sample surface at the position of the

WebWhen this happens, a water molecule, (H2O), loses a hydrogen atom to become OH− and H+. The hydrogen ion then joins with another water molecule to form hydronium, (H3O+ ). Autoionization of water can happen when two water molecules collide and a hydrogen ion transfers from one molecule to the other.
