ABSTRACT:
The method of producing specific cluster ions utilizing an ionization source to produce ions which are then sorted or resolved according to velocity and mass. The selected ions are passed through a growth chamber containing a gaseous vapor of a specified element and are coated by the vapor to provide coated cluster ions. The coated cluster ions are mass selected and held in an ion trap.
