In 2007 the mass measurements at the tandem Penning trap mass spectrometer ISOLTRAP focussed on nuclear structure and nucleosynthesis studies. The masses of about 20 nuclides have been measured with relative mass uncertainties as low as 1*10-8. The beam times were dedicated to the mass determination of neutron deficient and neutron rich nuclides relevant for the investigation of the rp- and...

JYFLTRAP and IGISOL-facility has been in high-precision operation now for few years producing vast amount of atomic mass data for nuclear structure studies and fundamental physics. All in all more than 200 atomic masses of ground and isomeric states has been measured from sub-keV to few keV precision. In this contribution the recent highlights from the facility will be reviewed and few...

We present in detail the status of the WITCH experiment (Weak Interaction Trap for Charged particles). The primary aim is to investigate exotic weak currents in nuclear beta decay by measuring a recoil ion spectrum and deriving the beta neutrino angular correlation coefficient from its shape. At the end of the year 2006, we succeeded for the first time in measuring a recoil ion spectrum using...

The TRIGA Mainz research reactor offers unique possibilities for online mass measurements on neutron-rich isotopes as produced by fission of U-235, Pu-239 or Cf-249 targets. A new Penning trap mass spectrometer will be installed, featuring not only the commonly used time-of-flight resonance technique, but also the non-destructive narrow-band image current technique, enabling the detection of a...

The ISOLTRAP experiment has up to now provided precise values of masses of more than 300 radionuclides with relative uncertainty below 10-7 and many cases reaching 10-8. Presently, there are two main projects under way at ISOLTRAP, which aim at widening the number of nuclides to study and the type of the performed measurements. The first is devoted to studying masses of halo nuclei, which...
