| Abstract | Accounting for the appearance of new magic numbers represents an exacting test for nuclear models. Binding energies o er a clear signature for the presence (or dis- appearance) of shell closures. To determine the strength of the purported N = 32 shell closure, we propose using the Penning-trap spectrometer ISOLTRAP for mass measure- ments of N = 34 isotones 58 Cr ( Z = 24), 55 Sc ( Z = 21) and 54 Ca ( Z = 20), as well as the N = 32 isotones 53 Sc and 52 Ca. We also propose measuring the mass of 60 Cr to test the shell model prediction of a new magic number at N = 34. In addition to the Penning-trap system at ISOLTRAP, we intend to use the newly commissioned multi-re ection time-of- ight mass separator, which enables direct mass measurements on nuclei with half-lives below 50 ms. |
