THE possibility that fundamental nuclear constants may vary slowly while the Universe expands has been discussed by several authors1–5. I try here to show that the well known resonance properties of the ‘heavy nucleus plus slow neutron’ system make it a sensitive ‘receiver’, sharply tuned to the current values of nuclear constants. 
Testing the variation of fundamental constants with astrophysical and spectroscopic data
In many theories of unified interactions, there are additional degrees of freedom that may allow for the variation of the fundamental constants of nature. I will review the motivation for and
Were fundamental constants different in the past
Atomic physics, nuclear physics, and cosmology enable physicists to probe changes in the fine-structure constant over time scales ranging from a few years to nearly the age of the universe.
Is the weak interaction constant really constant?
A comparison is made of the probability of the process of two-neutrino double beta decay for 82Se and 96Zr in direct (counter) and geochemical experiments. The experimental data for 130Te are also
Variations of the coupling constants of fundamental interactions in Dirac's cosmology
It is pointed out that several interesting coincidences and relationships connecting the parameters of cosmology and elementary particle physics suggest that the coupling constants of the weak,
Does the weak interaction constant depend on time?
A comparison is made of the probability of the process of two-neutrino double β decay for 82Se and 96Zr in direct (counter) and geochemical experiments. The experimental data for 130Te are analyzed.

The probabilities of the two-neutrino double-beta decay of 82 Se and 96 Zr in direct (counter) and geochemical experiments are compared. Relevant experimental data on 130 Te are also analyzed. It is
Search for a possible variation of the fine structure constant
The determination of the fine structure constant α and the search for its possible variation are considered. We focus on the role of the fine structure constant in modern physics and discuss

THE fundamental constants of physics, such as c the velocity of light, h Planck's constant, e the charge and m mass of the electron, and so on, provide for us a set of absolute units for measurement
Time Variation of the Charge of the Proton
From the terrestrial occurrence of the nuclei ${\mathrm{Re}}^{187}$ and ${\mathrm{Os}}^{187}$, it is deduced that the elementary unit of charge $e$ cannot have varied by as much as one part in 1600
