Abstract:

With the aid of microscopic theory of collective excitations in spherical odd-mass nuclei proposed by Kuriyama, Marumori and Matsuyanagi, structures of low-lying collective 5/2⁺ states in odd-mass, I, Cs and La isotopes and of collective 3/2⁺ states in odd-mass Mo and Ru isotopes are investigated. These collective 5/2⁺ and 3/2⁺ states, which are hard to understand within the framework of the conventional quasi-particle-phonon-coupling theory, are identified as a new kind of fermion-type collective excitation mode. The change in microscopic structure of these states depending on the mass number is also investigated in relation with the shell structure.
