The ubiquitous spectroscopic problem of decomposing overlapping lines is solved for ion scattering spectroscopy employing Maximum Entropy. The chosen example of Pd adsorption on a Ru surface is particularly challenging because 13 partially overlapping isotopes contribute to the total scattering signal. Proper decomposition using appropriate prior information enables accurate coverage determination.
