Hyperfine 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 $^{11}$Be is obtained by using the core plus neutron type wave function: $ |2s_{1\over 2}>+|1d_{5\over2}\times 2^+ ; {1/2}^{+}> $. A large hfs anomaly of $^{11}$Be is found, which is mainly due to a large radius of the halo single particle state.

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 universality check of the M-L formula.
