Identification of fragment ions produced by the decomposition of tetramethyltin and the production of low-energy Sn+ ion beam.
Tetramethyltin was decomposed in an ion source and the fragment ions produced were identified using a low-energy mass-selected ion beam machine.Dominant fragment ions were found to be H+, CH2+, and Sn+.Subsequently, fragment ions were mass-selected.The mass spectrum of the selected ions indicated that only a single peak appeared at the mass number
