Fine structure of atoms
WebJul 4, 2000 · When the atoms are detected falling back down to the original 2 3 P 1 state, this signals that the microwave frequency corresponded to the small fine structure interval n 12. A major complication with the measurement is a smearing out of the energy of the states connected with their decay. WebThe fine-structure constant of the universe is part of the definition of electromagnetic attraction. In a universe where the constant is a fraction higher, electrons would orbit closer to the atomic nucleus, which means atoms would never clump together; a fraction lower would make electrons orbit farther out and everything would glue together.
