Further analysis of the IRIS iron isotope experimentThe IRIS Fe isotope experiment was extended to atomic charges of Z = 19, with isotopic distributions for 500 events ranging from 18 to 28. Normalization of the detector response functions at Fe-56 produced a single well resolved peak at Sc-45, establishing the resolution and mass scale of the device over the entire charge region. The abundance distributions for the predominantly primary isotopes Ca-40, Fe-54, Fe-56, Ni-58, and Ni-60 do not indicate a large admixture of material with distinctly nonsolar abundances.
