摘要：

Penning ion traps are used as mass spectrometers for high precision determination of mass doublets. We present our experimental setup and discuss in detail possible sources of systematic uncertainties from electric and magnetic field distortions, misalignments and ion-ion interaction. Methods are discussed to deal with the associated line shifts. As a result, we demonstrate experimentally obtained resolutions of a few parts in 10-9 for light masses. The method allows very precise determinations of doublet mass differences of light ions. © 1990.
