Nuclear level mixing resonances (LMR)

The recently developed Level Mixing Resonance method for the measurement of hyperfine interactions turns out to be a very useful complement to the other methods. Especially in the “difficult” cases, e.g. When the lifetime of the isomer under consideration is very long or when its spin is very high, this new method can yield valuable, otherwise inaccessible, information. In this paper the concept of this method is briefly presented and some of the recent experiments are described.
