Direct mass measurements on the superallowed emitter 74Rb and its daughter 74Kr: isospin-symmetry-breaking correction for standard-model tests.
The decay energy of the superallowed beta decay 74Rb(beta+)74Kr was determined by direct Penning trap mass measurements on both the mother and the daughter nuclide using the time-of-flight resonance technique and was found to be Q=10 416.8(4.5) keV. The exotic nuclide 74Rb, with a half-life of only 65 ms, is the shortest-lived nuclide on which a high-precision mass measurement in a Penning trap...
متن کاملHigh precision half - life measurement of the superallowed β - emitter 38 Ca
We have now analyzed the results obtained from our half-life measurement of Ca. In that measurement, we produced Ca via the H(K, 2n) reaction at a primary beam energy of 30A MeV. A 99%-pure Ca beam was obtained at the focal plane of the MARS spectrometer, from which it exited the vacuum system through a 50-μm thick Kapton window, passed through a 0.3-mm-thick BC404 scintillator and a stack of a...

V.E. Iacob, V. Golovko, J. Goodwin, J.C. Hardy, N. Nica, H.I. Park, L. Trache, and R.E. Tribble The half-life of C was measured as part of our program to test the unitarity of the CabibboKobayashi-Maskawa (CKM) matrix via 0 –> 0 superallowed β transitions; the case of C is of particular interest because of its higher sensitivity to the presence of scalar currents [1]. The C half-life has been m...
