Abstract

We propose to use a Penning trap for spectroscopy of stored cluster ions. A similar device has been built by us for the purpose of mass measurements of short-lived nuclei produced at the on-line isotope separator ISOLDE/CERN. A resolving power of 500,000 in a mass measurement of 39K and an accuracy of 2×10−7 for the 85Rb/39K mass ratio were obtained. An efficiency for in-flight capture as high as 70% was achieved. A method of very high sensitivity is realized since typically only 10 to 100 ions are stored in the trap. We intend to perfom laser spectroscopy on trapped Na cluster as a first application of the trap technique.
