Translational energy release in the decomposition of metastable ions

3 Translational energy release in the decomposition of metastable ions 

Consider a single-valued translational energy release, T, in the decomposition of a metastable ion M+ in a field-free region to give a product ion m+. The spread in translational energy (AeV) of m+ along the original direction of motion can be expressed as [186]
