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
متن کاملHyperfine Structure and Tunneling Motion in Ethylenediamine
The first investigation of the microwave spectrum of ethylenediamine (NH CH –CH NH ) showed that in the gas phase this molecule occurs in two conformers which both exhibit a large amplitude tunneling motion corresponding to an interchange of the roles of the amino groups. In conformer I, the tunneling splitting is about 172 MHz while it is only 2.7 MHz in conformer II. In the paper an analysis ...
متن کاملPrecise fine-structure and hyperfine-structure measurements in Rb
We demonstrate a new technique for measuring the absolute frequencies of atomic transitions. The technique uses a ring-cavity resonator whose length is calibrated using a reference laser locked to the D2 line in Rb. The frequency of this line is known to be 384 230 484.468(10) MHz. Using a second laser locked to the D1 line of Rb, we measure the frequencies of various hyperfine transitions in t...
متن کاملHyperfine Structure Constants for Diatomic Molecules
The multiconfiguration valence-bond method (VB) is applied to diatomic molecules using the Hartree-Fock (HF) atomic basis set. The hyperfine constant, Fermi contact term, is computed as a function of the interatomic separation for the X2∏ ground state of 17OH and X1∑ ground state of 107AgH+ molecules. This study leads to a number of conclusions about the influence of correlation and polarizatio...
