New Band Structures in A∼110 Neutron-Rich Nuclei.

The high spin states of neutron-rich nuclei in A∼110 region have been carefully investigated by measuring prompt γ-γ-γ coincident measurements populated in the spontaneous fission of ²⁵²Cf with the Gammasphere detector array. Many new collective bands have been discovered. In this proceeding paper, we introduce some interesting new band structures recently observed by our cooperative groups, that is, the one-phonon- and two-phonon γ-vibrational bands in odd-A ¹⁰³Nb, ¹⁰⁵Mo and ¹⁰⁷Tc, the chiral doublet bands in even-even ¹⁰⁶Mo, ¹¹⁰Ru and ¹¹²Ru, and the pseudospin partner bands with in ¹⁰⁸Tc. The characteristics of these band structures have been discussed. [ABSTRACT FROM AUTHOR]
