Description

ISOLTRAP is a Penning trap mass spectrometer installed at ISOLDE/CERN for on-line mass measurements of short-lived nuclides. The determination of nuclear binding energies with an uncertainty of 10^-8 on nuclides that are produced with yields as low as a few 100 ions/s and at half-lives well below 100 ms demonstrate the prominent role of our experiment. A number of scientific highlights have been obtained recently, as e.g. the mass measurement of ³²Ar (T_1/2 = 98 ms) and ⁷⁴Rb (T_1/2 = 65 ms). Both provide important input for fundamental tests of the weak interaction, like test of the conserved vector current (CVC) hypothesis and the unitary of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The status of ISOLTRAP as well as recent results will be presented.
