Explanation

It is also called superconductor isotope effect. In 1950, Maxwell, Reynolds, and Selin simultaneously discovered a relationship between the critical temperature of superconductors and isotopic mass. The higher the mass of the selected isotope for the same element, the lower the critical temperature. The isotope effect of superconductors shows that the process of transformation from the publicly owned electrons to the ordered state of superconducting electrons reflects the influence of lattice lattice motion properties. Therefore, it is necessary to consider two aspects: lattice lattice motion and public electrons. This discovery gave a lot of inspiration to the later BCS theory.
