Description

We have systematically investigated highly-K-forbidden transitions observed in the Hf, W and Os region, using the γ-tunneling model in which low-K and high-k states interact through a process of quantum tunneling. The measured hindrance factors are compared with the values calculated using the γ-tunneling model. Isotope dependences of γ-tunneling probabilities particularly for neutron-rich nuclei and the relation to stimulated decays of isomers are discussed. (author)
