Hyperfine Anomaly of Be Isotopes and Anomalous Large Anomaly in ${}^{11}$Be

Abstract

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: $|2s_{\frac{1}{2}}>+|1d_{\frac{5}{2}}\times 2^{+};{1/2}^{+}>$. A large hfs anomaly of ${}^{11}$Be is found, which is mainly due to a large radius of the halo single particle state.
