Abstract

In this paper some new unpublished mass-spectrometric measurements on sodium isotopes will be presented. In AMCO V1 mass measurements for A = 26 to 32 were already presented and had shown the onset of a deformation for A = 31 and 32. This had encouraged us to pursue these experiments in order to investigate what happens for isotopes further from stability: 33Na which was already observed to be bound but for which the mass could not be measured, and 34Na, the existence of which was questionable according to predictions. In addition, it seemed also important to improve the precision on 31,32Na for which an error bar of 1 MeV had been obtained while the observed anomaly was 2–4 MeV only.
