The high-spin states of the odd-odd nucleus 170Ta have been studied by the 155Gd (19F, 4n) 170Ta reaction at the beam energy of 97 MeV. The α = 1 sequence of the semi-decoupled band has been pushed to higher-spin states and the signature inversion point was observed at 19.5h. The results are compared with those of the neighbouring odd-odd nuclei.
