Accurate mass measurements of ²⁶Ne, ²⁶⁻³⁰Na, ²⁹⁻³³Mg performed with the Mistral spectrometer

Original · EN

The minuteness of the nuclear binding energy requires that mass measurements be highly precise and accurate. Here we report on new measurements ²⁹⁻³³Mg and ²⁶Na performed with the Mistral mass spectrometer at Cern's Isolde facility. Since mass measurements are prone to systematic errors, considerable effort has been devoted to their evaluation and elimination in order to achieve accuracy and not only precision. We have therefore conducted a campaign of measurements for calibration and error evaluation. As a result, we now have a satisfactory description of the Mistral calibration laws and error budget. We have applied our new understanding to previous measurements of ²⁶Ne, ²⁶⁻³⁰Na and ²⁹,³²Mg for which re-evaluated values are reported.
