摘要：

The mass of the short-lived radio nuclide Ca-38 (T-1/2=440 ms) has been measured with the 9.4-T Penning trap mass spectrometer of the Low-Energy Beam and Ion Trap Facility. A mass uncertainty of delta m=280 eV has been achieved, corresponding to delta m/m=8x10(-9). The result makes Ca-38, a superallowed beta emitter, a new candidate to test the conserved-vector-current hypothesis. The experiment is also the first demonstration that short-lived radioactive isotopes produced by projectile fragmentation of relativistic heavy-ion beams can be slowed down and prepared such that precision experiments of this kind are possible.
