Description
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 provide important input e.g. for deriving their charge radii. Since the present cooling scheme using helium is not effective for such light nuclides, hydrogen cooling has to be used instead, and necessary simulations and tests are presently under way. The other development will allow using ISOLTRAP for isobaric and even isomeric purification to performing beta- and gamma-decay studies. Presently, the setup is being prepared for the measurements on neutron-rich Hg and Tl isotopes beyond N=126. In this talk I will present the physics motivation of these two developments, their status and future plans.
