摘要：

As one of the fashionable techniques for nuclear spectroscopy experiments, the beam manipulation in gas-filled Penning traps permits the accurate measurement of some of the ground state properties of exotic nuclides. It wits recently applied using REXTRAP for the measurement of the half-life of Ca-38, one of the 0(+)-> 0(+) beta-decaying nuclide of interest for the determination of the Ft value for super-allowed transitions, and the test of the unitarity of the CKM matrix. The experimental setup and the original method of beam purification adopted for this measurement is presented. (c) 2008 Elsevier B.V. All rights reserved.
