Description
The ISOLTRAP mass spectrometry program at ISOLDE has pioneering many developments over the past decades, the most recent being the combination of precision time-of-flight mass spectrometry and in-source laser-ionization scanning to obtain the hyperfine structure of the isotope of interest.
First developed using sensitive alpha spectroscopy, the successful in-source spectroscopy technique was considerably extended by counting ions instead of radioactivity. Moreover, the high-resolution offered by ion traps enabled a dramatic gain in sensitivity not possible with dipole mass separators.
This contribution will recall the development of the in-source MS technique with some of the highlights before presenting new mass-spectrometry results for neutron-rich mercury (212Hg) and neutron-deficient cadmium (97Cd), both of which are near the intersections of major shell closures.
