New mass measurements with the ISOLTRAP spectrometer

摘要

The Penning trap spectrometer ISOLTRAP at the on-line mass separator facility ISOLDE/CERN has been employed for mass measurements of more than 200 unstable nucvlei. Examples for recent ISOLTRAP measurements on very short-lived isotopes are the precise determination of the mass of ~(33)Ar, which provides a test of the Isobaric Multiplet Mass Equation (IMME), and of ~(34)Ar and ~(74)Rb, which are both important in the context of fundamental weak interactions studies. Isotopes in the vicinity of doubly-magic ~(132)Sn have been investigated as well as the mass of the rp-process waiting point candidate ~(76)Sr.
