    摘要: A positive ion of an isomer is generated in an ion source and introduced into a target chamber filled with a target alkali metal so that it is dissociated into a neutral fragment which is then subjected to charge inversion to generate a negative ion. By measuring the mass spectrum of the negative ion, the isomer can be detected at a higher resolution than has been possible by CID and other conventional mass spectroscopic techniques.
