Theoretical corrections and world data for the superallowed ft values in the beta decays of 42Ti, 46Cr, 50Fe and 54Ni

I. S. Towner, J. C. Hardy

Prompted by recent measurements, we have surveyed world data and calculated radiative and isospin-symmetry breaking corrections for the superallowed 0+ -to- 0+ Fermi transitions fr…

Parameterization of the statistical rate function for select superallowed transitions

I. S. Towner, J. C. Hardy

We present a parameterization of the statistical rate function, f, for 20 superallowed 0+-to-0+ nuclear beta transitions between T=1 analog states, and for 18 superallowed "mirror"…

Vud from Nuclear Decays

I. S. Towner, J. C. Hardy

The current value of Vud is determined from superallowed beta-decay experiments. Other methods, briefly summarised here, have to overcome specific experimental hurdles before they…

Comparative tests of isospin-symmetry-breaking corrections to superallowed 0+-to-0+ nuclear beta decay

I. S. Towner, J. C. Hardy

We present a test with which to evaluate the calculated isospin-symmetry-breaking corrections to superallowed 0+-to-0+ nuclear beta decay. The test is based on the corrected experi…

An improved calculation of the isospin-symmetry-breaking corrections to superallowed Fermi beta decay

I. S. Towner, J. C. Hardy

We report new shell-model calculations of the isospin-symmetry-breaking correction to superallowed nuclear beta decay. The most important improvement is the inclusion of core orbit…

A new analysis of 14O beta decay: branching ratios and CVC consistency

I. S. Towner, J. C. Hardy

The ground-state Gamow-Teller transition in the decay of 14O is strongly hindered and the electron spectrum deviates markedly from the allowed shape. A reanalysis of the only avail…
