Abstract High spin states in 174Re are investigated via the 152Sm(27Al,5nγ)174Re reaction and γ-γ coincidence relationships are analysed carefully. A new band is identified due to its spectroscopic connection with the known π1/2-[541]⊕ν1/2-[521] band. This band is proposed to be the ground-state band built on the π 1/2- [541]⊕ν5/2- [512] configuration in view of the low-lying intrinsic states in the neighbouring odd-mass nuclei. It is of particular interesting
that the new band exhibits a phenomenon of low-spin signature inversion,
providing a new situation for theoretical investigations.
