Magnetic moments and in-beam hyperfine interactions group
Interactions between the electric and magnetic fields produced by the nucleus and the local electric and magnetic fields in the immediate surroundings of the nucleus are called hyperfine interactions. It is these hyperfine interactions that we measure with a view to learning more about either the internal workings of the nucleus or about the fields in which the nucleus is placed.
This work is related to both the nuclear spectroscopy and the perturbed angular correlations activities of the Department. In cases where the fields applied to the nucleus are known we can obtain new information about the fields produced by the nucleus. These fields are usually characterized by quantities known as the magnetic dipole moment and the electric quadrupole moment. By measuring these moments for individual quantum states of the nucleus we can learn about their internal structure.
