Power for the ratio of mass intensities in two mass spectra measured for two different
primary ion conditions, used to generate the
G-SIMS spectrum.
Notes: - The different primary ion conditions can be two, well-separated, energies for the same primary ion or two different primary ions, usually at the same beam energy.
- A value of 13 has been found to be effective for the g index in generating G-SIMS spectra and a continuous variation between 0 and 40 for analysis.
