Hyperfine Structure Constants for Eu Isotopes : Is The Empirical Formula of HFS Anomaly Universal ?
We calculate the hyperfine structure constant for the Eu isotopes with shell model wave functions. The calculated results are compared with those predicted by the Moskowitz-Lombardi (M-L) empirical formula. It turns out that the two approaches give the very different behaviors of the hfs constants in the isotope dependence. This should be easily measured by experiment, which may lead to the uni...

متن کاملOn the hyperfine anomaly in Eu isotopes
A new method for determining the hyperfine anomaly, without knowing the nuclear magnetic moment, is used for the first time on a series of unstable isotopes. The relative large number of experimental data in Eu makes it possible to determine the hyperfine anomaly for a number of unstable isotopes. Calculations of the Bohr-Weisskopf effect and hence the hyperfine anomaly has been performed using...
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...
متن کاملHyperfine Anomaly of Be Isotopes and Anomalous Large Anomaly in 11 Be
A new result of investigations of the hyperfine structure (hfs) anomaly in Be isotopes is presented. The hfs constant for Be is obtained by using the core plus neutron type wave function: |2s 1 2 > +|1d 5 2 × 2; 1 2 + >. A large hfs anomaly of Be is found, which is mainly due to a large radius of the halo single particle state. PACS numbers : 21.10.Ky, 21.60.Cs, 27.20.+n, 33.15.Pw
