WebThe separations among various components of a hyperfine structure are usually small enough to fit into the receiver's IF band. Nuclear technology: The atomic vapor laser isotope separation (AVLIS) process uses the hyperfine splitting between optical transitions in uranium-235 and uranium-238 to selectively photo-ionize only the uranium-235 atoms … WebOptical hyperfine structure was observed as early as 1891 by A.A. Michelson. In order to account for this, Pauli proposed in 1924 that the atomic nucleus possesses a small magnetic moment. In 1935, study of hyperfine structure anomalies led M. Schiiler and T. Schmidt to propose the existence of a nuclear quadrupole moment. WebThe hyperfine structure also relies on the electron-nucleus wave functions overlap, which means that we can judge the accuracy of PNC calculations by determining the hyperfine coupling constants (HCCs) precisely [2, 3]. Moreover, precise measurement of atomic hyperfine structure can also provide more accurate benchmarks in high-precision field. bowhill kettering

WebThe theory of hyperfine structure comes directly from electromagnetism, consisting of the interaction of the nuclear multipole moments (excluding the electric monopole) with internally generated fields. The theory is derived first for the atomic case, but can be applied to each nucleus in a molecule. WebOld high-precision frequency standards, i.e. hyperfine structure transition-based atomic clocks, may require periodic fine-tuning due to exposure to magnetic fields.
