On the Q-value of the tritium β-decay
– We report here the atomic masses of H and He determined by using the Penning trap mass spectrometer Smiletrap. The measurements are based on cyclotron frequency determinations of H and He using H+2 ions as mass reference. The mass values for H and He are 3.016 049 278 7(25) u and 3.016 029 321 7(26) u, respectively. From these masses a new Q-value of the tritium β-decay was derived resulting ...
متن کاملSuperallowed beta decay
Superallowed 0 → 0 beta decay between T=1 analogue states has been a subject of continuous and often intense study for five decades. The ft values of such transitions are nearly independent of nuclear-structure ambiguities and depend uniquely on the vector part of the weak interaction. Their measurement gives us access to clean tests of some of the fundamental precepts of weak-interaction theor...
متن کاملSuperallowed Fermi Beta Decay
Superallowed 0 → 0 nuclear beta decay provides a direct measure of the weak vector coupling constant, GV. We survey current world data on the nine accurately determined transitions of this type, which range from the decay of C to that of Co, and demonstrate that the results confirm conservation of the weak vector current (CVC) but differ at the 98% confidence level from the unitarity condition ...

Masses of the radioactive isotopes Ga, Zn and Cu have been measured at the JYFLTRAP facility with a relative precision of better than 1.8× 10. A QEC value of (9181.07 ± 0.54) keV for the superallowed decay of Ga is obtained from the measured cyclotron frequency ratios of Ga—Zn, Ga—Ni and Zn—Ni ions. The resulting Ft-value supports the validity of the conserved vector current hypothesis (CVC). T...
متن کاملBeta-decay branching ratios of 62Ga
Beta-decay branching ratios of Ga have been measured at the IGISOL facility of the Accelerator Laboratory of the University of Jyväskylä. Ga is one of the heavier Tz = 0, 0 → 0 β-emitting nuclides used to determine the vector coupling constant of the weak interaction and the Vud quark-mixing matrix element. For part of the experimental studies presented here, the JYFLTRAP facility has been empl...
