The Universe

It has long been recognized that Dirac's principle might imply that the rate of β decay would vary with the age of the universe. If so, the radioactive ages of meteorites and terrestrial rocks as indicated on the one hand by α decay and on the other by β decay should differ. However, the comparison of these ages is complicated by a large uncertainty in the decay constant for Rb87. Thus the age data must be analyzed to determine the decay constant most compatible with the particular theory of β decay which is used. Using this best decay constant for each theory, we find that the data are more consistent with a β decay rate independent of the age of the universe than with the dependence implied by the Dirac principle.

Status Effect

Recently, a reproducible reactor-status effect was measured for the decay of [Formula: see text]Na. However, the effect was not observable for the [Formula: see text] decay of [Formula: see text]Co. Since no systematic cause for this effect was found, the possibility exists that it is caused by an interaction of reactor antineutrinos with the source nucleus. The observed effect is 18 orders of magnitude larger than for the antineutrino capture of a free proton. A possible explanation is a final-state interaction between the incoming antineutrino and a neutrino in the source nucleus. The effect has still to be confirmed by an independent measurement. In this paper, the consequences for applications in monitoring nuclear facilities are discussed, as well as the consequences for fundamental physics and the opportunities for resolving some outstanding questions about neutrino properties.

Plane Wave Field

The possibility of influencing nuclear beta decay with high intensity optical lasers is examined numerically with the appropriate exact wave functions of a Dirac electron in a plane-wave field, as in previous literature. The total β-decay rate for 3H is found to be unaffected by the laser field for a 2-eV laser with intensities in the range 1018–1020 W/cm2.
