Induced γ radiation of High K Isomer States of Nuclei

Key words: 
• induced γ-emission /
• nuclear isomer state /
• K-mixing state

Abstract: The nuclear isomer states have great potential value of application. The important experimental and theoretical researches are presented here. There are three kinds of physics mechanism for the formation of the isomer states. The principle of releasing the energy stored in the isomer is to excite it to higher states, Kmixing states, which can spontaneously decay to the ground state forming the γcascade. After introducting the three ways to form the Kmixing states, we analyzed experiments on the most prospective isomer ¹⁷⁸Hf^m2, discussed the key differences between these experiments and suggested that the Projected Shell Model (PSM) can be helpful to confirm the occurrence of the  Kmixing states and would work out characteristics of the induced decay.
