A model for the behavior of closely spaced masses the “mass multiplet” –in a Penning trap mass spectrometer is developed. The model shows how these species separate from each other (or not) following resonant excitation. Quantitative criteria for mass separation are developed. More surprisingly, the model shows the species tend to drift to different mean cyclotron radiu. This latter effect undoubtedly plays a role in the abundance determinations in Penning trap mass spectrometers.
