Abstract：
The high spin states of the neutron-rich odd-odd ¹⁰⁶Tc nucleus have been reinvestigated by observing prompt γ-rays from the spontaneous fission of ²⁵²Cf. A previously known collective band is confirmed and expanded, and a new collective band is newly identified. Several levels in previous report in ¹⁰⁶Tc are reexamined and they belong to the members of a band in ¹⁰⁷Tc. The total Routhian surface (TRS) calculations show that the ¹⁰⁶Tc has triaxial shape. The spins and parities as well as the configurations for these bands have been tentatively assigned according to the analysis of the angular momentum alignments.
