Atomic Hyperfine Splitting in Rubidium
In its ground state, rubidium (Rb) has a single 5s electron outside a closed shell; the principal structure of its excited states is therefore similar to that of hydrogen. The first excited state is split in two by the spin-orbit interaction, and each of these levels is split further by the hyperfine interaction. Neglecting relativistic and reduced-mass effects, the Hamiltonian consists of four...
متن کاملMeasurement of the hyperfine splitting of the 6S1Õ2 level in rubidium
We present a measurement of the hyperfine splitting of the 6S1/2 excited level of rubidium using two-photon absorption spectroscopy in a glass cell. The values we obtain for the magnetic dipole constant A are 239.18 03 MHz and 807.66 08 MHz for Rb and Rb, respectively. The combination of the magnetic moments of the two isotopes and our measurements show a hyperfine anomaly in this atomic excite...
متن کاملLifetime and hyperfine splitting measurements on the 7s and 6p levels in rubidium
We present lifetime measurements of the 7S1/2 level and the 6p manifold of rubidium. We use a timecorrelated single-photon counting technique on a sample of 85Rb atoms confined and cooled in a magneto-optic trap. The upper state of the 5P1/2 repumping transition serves as the resonant intermediate level for twophoton excitation of the 7s level. A probe laser provides the second step of the exci...
متن کاملHyperfine Splitting of Hydrogenlike Thallium
The investigation of hydrogenlike highly-charged ions is of interest for nuclear as well as for atomic physics. Measuring the ground-state hyperfine structure (HFS) splittings of these ions is a sensitive method to explore QED in extremely strong electric and magnetic fields and nuclear contributions to the electron energy. However, for a theoretical interpretation of the results it is necessar...
متن کاملHyperfine splitting in lithiumlike scandium
High-precision experiments on the ground state hyperfine splitting in highly charged ions performed at the GSI facilities and at the EBITs (see, e.g., Refs. [1, 2, 3]) have triggered intensive theoretical investigations of this effect. The error bars of the theoretical hyperfine splitting values are mainly determined by the nuclear magnetization distribution correction, the so-called Bohr-Weiss...
