New mass measurements with the ISOLTRAP spectrometer.

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 nuclei. Examples for recent ISOLTRAP measurements on very short-lived isotopes are the precise determination of the mass of [sup 33]Ar, which provides a test of the Isobaric Multiplet Mass Equation (IMME), and of [sup 34]Ar and [sup 74]Rb, which are both important in the context of fundamental weak interactions studies. Isotopes in the vicinity of doubly-magic [sup 132]Sn have been investigated as well as the mass of the rp-process waiting point candidate [sup 76]Sr. © 2002 American Institute of Physics.
