“…For r > R 0 the distribution function F (r) = 1. In the case of 14 N with I = 1 we follow the work [11] and assume that the nuclear magnetization is determined by the odd proton and neutron. The corresponding formulas for ε were derived in Refs.…”

“…However, with the sphere model one can not always describe adequately the nuclear magnetization distribution. The approximation of the nuclear single-particle model is widely used for the evaluation of the Bohr-Weisskopf correction [10,11,12,27,28,29,30].…”

“…The first accurate calculation (∼ 0.1%), based on a combination of 1/Z perturbation theory and the nonrelativistic configuration-interaction HartreeFock method, was performed in Refs. [11,12]. Later, Boucard and Indelicato [13] employing the multi-configuration Dirac-Fock method presented the evaluation of the hyperfine splitting values over the entire range of the nuclear charge numbers Z = 3 − 92.…”

The hyperfine splitting of the ground state of H-, Li-, and B-like ions is investigated in details within the range of nuclear numbers Z = 7 − 28. The rigorous QED approach together with the large-scale configuration-interaction Dirac-Fock-Sturm method are employed for the evaluation of the interelectronicinteraction contributions of first and higher orders in 1/Z. The screened QED corrections are evaluated to all orders in αZ utilizing an effective potential approach. The influence of nuclear magnetization distribution is taken into account within the single-particle nuclear model. The specific differences between the hyperfinestructure level shifts of H-and Li-like ions, where the uncertainties associated with the nuclear structure corrections are significantly reduced, are also calculated.

“…In this case the lower "−" sign corresponds to the lower hyperfine level, and the upper "+" sign corresponds to the upper level. An accurate expression for the hyperfine splitting in a hydrogen-like ion can be found in [12]. For an estimate, one can use the approximate formula pendence.…”

We consider two possible schemes for generation and detection of a monoenergetic directed beam of neutrinos which may have application to neutrino communication. First, we consider generation of a directed neutrino beam using electron capture beta decay in hydrogen-like ions. Next, we suggest detection of a directed neutrino beam using resonant absorption of a neutrino by a bare nucleus with the generation of a bound electron. This reaction is inverse to electron capture beta decay, and we call it "Bound State Inverse Beta Decay (BSIBD)". We show that the recoil effect can be eliminated by an appropriate choice of velocities for the ions and bare nuclei. Finally, we consider a combination of a solid state source of a directed mono-energetic neutrino beam and its detection using BSIBD.

Spectroscopy performed with the three Livermore electron beam ion traps is reviewed, which is continuing and complementing the innumerable contributions to atomic physics provided over the years by heavy-ion accelerators. Numerous spectrometers were developed that cover the spectral bands from the visible to the hard x ray region. These enabled exhaustive line surveys useful for x-ray astrophysics and for systematic studies along iso-electronic sequences, such as the 4s-4p, 3s-3p, and 2s-2p transitions in ions of the Cu-I, Na-I, and Li-I sequences useful for studying QED and correlation effects as well as for precise determinations of atomic-nuclear interactions. They also enabled measurements of radiative transition probabilities of very long-lived (milli-and microseconds) and very short-live (femtosecond) levels. Because line excitation processes can be controlled by choice of the electron beam energy, the observed line intensities are used to infer cross sections for electron-impact excitation, dielectronic recombination, resonance excitation, and innershell ionization. These capabilities have recently been expanded to simulate x-ray emission from comets by charge exchange. Specific contributions to basic atomic physics, nuclear physics, and high-temperature diagnostics are illustrated.
