Abstract

Accelerator mass spectrometric methods have been used in a survey to study atomic negative ions. The study revealed the existence of copious and fragile hydride negative ions that spontaneously fragment to neutral and negatively charged constituents. Some hydride fragments create ambiguities that can mimic the elemental ion of interest, and can be eliminated only if adequate resolution is available during the post acceleration phase of AMS. An overview of this phenomena will be presented in this paper.
