    Abstract

    It is presented reasonings that the known methods of the nuclear chronometry of the astrophysical and cosmological process have to be revised and corrected, taking into account distinctions between lifetimes of the ground and excited states for radioactive nuclei and also the multiple alternations of the $\gamma-emission$ from excited states and consequent $\gamma-absorptions$ by ground states in large lumps of matter. As a result, the corrected "nuclear clocks" will indicate to smaller values of the durations of real decay processes
