Abstract: To the great scale of the universe age, 187 Re- 187 Os isotopic pair, which have very long half life, was used as a cosmic nuclear clock of cosmochronometr. It is a typical relationship between modern astronomy and nuclear physics. The neutral isotope abundance ratio of 187 Re over daughter nucleus 187 Os in common growth mineral can be used as the clock to measure the time. After the 75 electrons in all shells of 187 Re were stripped ...
