74Rb Isotope Shift

74Rb is one of the few odd-proton, odd-neutron nuclides which violates the normal predictions of the nuclear shell model by having a spin-zero (0+) ground state. Nevertheless, two theoretically possible 0+ configurations exist for 74Rb, and it is unknown which one makes up its ground state...

Francium Hyperfine Anomaly

For light elements it is usually sufficient to treat the nucleus as a point with a pure dipole field when calculating hyperfine splitting. As the radius of the nucleus increases, however, the hyperfine coupling constant, A, deviates from the value expected by point-nucleus calculations. This is known as the Bohr-Weisskopf effect, or hyperfine anomaly...

β-NQR with 11Li

11Li consists of a core of 9Li surrounded by a two-neutron cloud, or “halo”, that gives it a nuclear matter radius similar to that of a lead nucleus....
