Charge exchange (or charge exchange collision) is a process in which a neutral atom or molecule collides with an ion, resulting in the neutral atom acquiring the charge of the ion. [1] The reaction is typically expressed as
Charge-exchange ionization (also known as charge-transfer ionization) is a gas phase reaction between an ion and an atom or molecule in which the charge of the ion is transferred to the neutral species. [8] + + + +
Charge-exchange ionization (also called charge-transfer ionization) is a gas phase reaction between an ion and a neutral species A + + B → A + B + {\displaystyle A^{+}+B\to A+B^{+}} in which the charge of the ion is transferred to the neutral.
Charge-exchange chemical ionization. This is also similar to CI and the difference lies in the production of a radical cation with an odd number of electrons. The ...
Ionization (or ionisation specifically in Britain, Ireland, South Africa, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
An alkali-filled charge exchange cell (CEC) is used to neutralise the ion beam, before it is directed through a differential pumping region and deflector plates. [10] Here, the residual ions that weren't neutralised are deflected and dumped, and the neutral beam proceeds to the interaction region, kept at ultra high vacuum (10 −10 mbar). [11 ...
For example, consider charge exchange between a deuterium atom and a C +6 ion: if the electron is transferred to the n=7 energy level of the carbon ion, then the ion will emit radiation at discrete energies given by the difference in energy between the n=7 and n=6 levels, the n=6 and n=5 levels, the n=5 and n=4 levels, and so on (down to n=1 ...
Ion-exchange resin beads Ion-exchange column used for protein purification. Ion exchange is a reversible interchange of one species of ion present in an insoluble solid with another of like charge present in a solution surrounding the solid. Ion exchange is used in softening or demineralizing of water, purification of chemicals, and separation ...
