High-precision Penning trap mass measurements on the stable nuclide 27Al aswell as on the short-lived radionuclides 26Al and 38,39Ca have been performedby use of radiofrequency excitation with time-separated oscillatory fields,i.e. Ramsey's method, as recently introduced for the excitation of the ionmotion in a Penning trap, was applied. A comparison with the conventionalmethod of a single continuous excitation demonstrates its advantage of up toten times shorter measurements. The new mass values of 26,27Al clarifyconflicting data in this specific mass region. In addition, the resulting massvalues of the superallowed beta-emitter 38Ca as well as of the groundstate ofthe beta-emitter 26Al m confirm previous measurements and correspondingtheoretical corrections of the ft-values.
