Proposed Chiral Doublet Bands in 98Tc

High spin states in odd-odd⁹⁸ Tc nuclei are studied by in-beam γ-ray spectroscopy with the ⁹⁶Zr(⁶Li, 4n) fusion-evaporation reaction at a beam energy of 35 MeV. The previous level scheme is updated. A band based on 1090.7 keV is expanded, and another band based on 1920.6 keV is newly identified. The observed two negative parity bands in ⁹⁸Tc are proposed to be a pair of chiral doublet bands with the configuration πg_9/2 otimes νh_11/2. The evidence supporting the assignment of the chiral doublet bands is discussed. Signature splitting and signature inversion are observed in the πg_9/2 otimes νh_11/2 band in ⁹⁸Tc.
