Calculation of exotic decay half-lives for all observed cases

Abstract

We extend the exotic decay half-life calculations of our previously reported model to include decays from odd-A nuclei and decays where the experimental determination of the mass of the emitted ion is ambiguous. We also present calculations for the decay 114Ba to 102Sn+12C which is currently being studied, so that we have now made predictions for the half-lives of all exotic decays for which positive experimental evidence of detection is extant. We find that the decays from even-even nuclei are well described by our model as ground-state to ground-state transitions, but that the decays from odd-A nuclei appear to involve predominantly an excited final state.
