Zusammenfassung:
The masses of 34Si, 33,34Mg, and 34Al have been measured with the ISOLTRAP Penning-trap spectrometer at ISOLDE/CERN. The results are in agreement with previous mass measurements and uncertainties have been decreased. The mass of 34Al was determined in two configurations, one following direct production by the ISOLDE facility, favoring the 4− state, expected to be the ground state, second by in-trap decay of 34Mg, followed by recoil-ion trapping, favoring the production of the isomeric 1+ state. A position-sensitive detector was used to clean the ToF-ICR resonance. In addition, the mass of the refractory doubly magic 34Si nucleus was directly measured, using the in-trap decay of 34Mg, following two sequential recoil-ion captures. The approach, challenges and conclusions are discussed.
