Trap-assisted decay spectroscopy with ISOLTRAP

摘要

Penning traps are excellent high-precision mass spectrometers for radionuclides. The high-resolving power used for cleaning isobaric and even isomeric contaminants can be exploited to improve decay-spectroscopy studies by delivering purified samples. An apparatus atlowing trap-assisted decay spectroscopy has been coupled to the ISOLTRAP mass spectrometer at 1S0LDE/CERN. The results from studies with stable and radioactive ions show that the setup can be used to perform decay studies on purified short-lived nuclides and to assist mass measurements.
