A Laboratory Experiment for Testing Space-Time Isotropy

TL;DR: In this article, a simple experiment to validate the principle of light isotropy is described, based on measurement of the ratio between refractive indices of two different optical media by using a collimated beam, which exploits the speed-of-light dependence of light propagating at an angle across optical interfaces and provides a means to test for light anisotropy with respect to a preferred reference frame.

Test of nuclear decay rate variation due to an antineutrino flux

- 14 Apr 2022 - 
TL;DR: In this paper , the authors reviewed the state of decay rate parameter variations experiments and placed them into a common comparable context by defining a phenomenological cross section, and then they made decay parameter measurements as a function of time at the level of $10.5$ in the presence of an antineutrino flux with an on-off cycle time of $30 days.

Variable radioactive decay rates and the changes in solar activity

Andrew Sibley
TL;DR: The authors found that there appears to be a correlation between the radioactive decay rate of 32Si and 226Ra on the earth and changes relating to the sun's activity, and such variable decay rates may have a bearing upon our understanding of the dating of various rock layers.

Evidence of correlations between nuclear decay rates and Earth–Sun distance

TL;DR: In this paper, the decay rates of 32 Si and 226 Ra have been investigated at Brookhaven National Laboratory (32 Si) and at the Physikalisch-Technische-Bundesanstalt in Germany (226 Ra).

Evidence against correlations between nuclear decay rates and Earth–Sun distance

TL;DR: In this article, the authors reexamined their previously published data to search for evidence of correlations between the rates for the alpha, beta-minus, beta plus, and electron capture decays of 22Na, 44Ti, 108Agm, 121Snm, 133Ba, and 241Am and the Earth?Sun distance.

Searching for modifications to the exponential radioactive decay law with the Cassini spacecraft

TL;DR: In this paper, the power output of the radioisotope thermoelectric generators aboard the Cassini spacecraft was used to test the conjecture that small deviations observed in terrestrial measurements of the exponential radioactive decay law are correlated with the Earth-Sun distance.

Expected signals in relic neutrino detectors

TL;DR: In this paper, the authors estimate the magnitude of the signals expected for realistic cosmic neutrino background in detectors attempting to measure the mechanical forces exerted on macroscopic targets by the elastic scattering of relic neutrinos.

The effective half-life of a broad beam 238Pu/Be total body neutron irradiator

TL;DR: In this paper, a broad-beam 238Pu/Be neutron irradiator has been previously developed for exclusive use in in vivo neutron activation analysis in humans and the initial calibrations of the facility provided only a fixed value for the thermal neutron flux.
