First results of a high precision mass measurement program for very short-lived nuclides

摘要

The recent commissioning of the experimental program MISTRAL (Mass Measurements at ISolde using a Transmission and Radiofrequency spectrometer oil Line) brought mass measurements of high precision performed on sodium and magnesium isotopes. The shortest half-life of an isotope treasured with MISTRAL was 30.5 ms (Na-28). Though this first period of data taking was dedicated to the exploration of MISTRAL performances it has allowed us to reduce the uncertainty in the mass of the Na28-30 isotope by almost one order of magnitude.
