Accurate mass measurements of ${}^{26}$Ne, ${}^{26-30}$Na, ${}^{29-33}$Mg performed with the {\sc Mistral} spectrometer

Abstract

The minuteness of the nuclear binding energy requires that mass measurements be highly precise and accurate. Here we report on new measurements ${}^{29-33}$Mg and ${}^{26}$Na performed with the {\sc Mistral} mass spectrometer at {\sc Cern}'s {\sc 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 {\sc Mistral} calibration laws and error budget. We have applied our new understanding to previous measurements of ${}^{26}$Ne, ${}^{26-30}$Na and ${}^{29,32}$Mg for which re-evaluated values are reported.
