Interrogating the composition and distribution of nuclear magnetization via the hyperfine anomaly: experiment meets nuclear and atomic theory for short-lived 47K
By combining high-precision liquid-state β-NMR measurements of short-lived 47K with advanced atomic and nuclear theories, this study successfully determines the spatial distribution of nuclear magnetization and reveals a persistent overestimation of spin contributions in current nuclear models, thereby establishing a robust method for benchmarking nuclear structure theory and searching for physics beyond the Standard Model.
