Proton capture cross section of Sr isotopes

open access: yesNuclear Physics A, 2001
The (p,gamma) cross section of Sr-84,Sr-86,Sr-87 isotopes has been measured using activation technique in the proton energy range between 1.5 and 3 MeV. These reactions are relevant to the p-process of stellar nucleosynthesis and in addition, the reaction cross sections in the mass region up to 100 are also important concerning the rp-process ...

Sr Isotopes in Seawater

2022
Studies of Sr isotopic composition of thousands of samples of marine sediments and fossils have yielded a curve of 87Sr/86Sr versus age for seawater Sr that extends back to 1 billion years. The ratio has fluctuated with large amplitude during this time period, and because the ratio is always uniform in the oceans globally at any one time, it is useful ...

New insights into the Sr isotope budget from stable-Sr isotope fractionation in gypsum

2023
The geochemical cycle of strontium (Sr) is closely tied to the long-term inorganic cycle of carbon since the budgets of both elements are controlled by similar natural processes such as volcanism, continental weathering, and carbonates precipitation.
