Systematic Behaviors of Signature Inversion in πh_(9/2)  vi_(13/2) Bands in A～170 Mass Region

摘要

Low-spin signature inversion in the πh9/2[?]vi_(13)/2 band was reported for the first time by Bark et al.~[1]in ^(162,164)Tm and ^(174)Ta in 1997.Since then,this inversion phenomenon has been found in several neighboring odd-odd nuclei.During the past few years,we have made great efforts to investigate the band structures
