Hyperfine field and hyperfine anomalies of copper impurities in iron

Hyperfine anomalies in Gd and Nd

The hyperfine anomalies in Gd and Nd have been extracted from the experimental hyperfine structure constants using a new method. In addition to the values of the hyperfine anomaly new improved values of the nuclear magnetic dipole moment ratios are derived. PACS Numbers: 21.10.Ky, 31.30.Gs, 32.10.Fn

Lattice relaxations and hyperfine fields of heavy impurities in Fe

We present first-principles calculations of the lattice relaxations and hyperfine fields of heavy impurities in bcc Fe. We consider impurities of the 5sp and 6sp series, containing the largest atoms in the periodic table. As an application we calculate the hyperfine fields of these impurities and in particular the effects of lattice relaxations on these fields. The calculations are based on a f...

Electronic structure and hyperfine parameters of substitutional Al and P impurities in silica

Hyperfine splittings in bottomonium

A universal description of the hyperfine splittings (HFS) in bottomonium and the Bq (q 1⁄4 n, s, c) mesons is obtained with a universal strong coupling constant sð Þ 1⁄4 0:310 in a spin-spin potential. Other characteristics are calculated within the field correlator method, taking the freezing value of the strong coupling independent of nf. The HFS MðB Þ MðBÞ 1⁄4 45:5ð1Þ MeV, MðB sÞ MðBsÞ 1⁄4 4...

Hyperfine Coupling Constants

The IH hyperfine coupling constants of free radicals and ions have been successfully studied by our newly modified s-p· separation type INDO-MO method->, and the most of our calculated coupling constants are significantly better than the corresponding results of the conventional INDO-MO method."" The nuclear hyperfine coupling constant is assumed to be directly proportional to the 2s spin densi...
