Abstract：
Search for low-spin signature inversion in the πi_13/2⊙νi_13/2 bands in odd-odd ^182,184,186Au has been conducted through the standard in-beam γ-spectroscopy techniques via the ¹⁵²Sm(³⁵Cl,5n)¹⁸²Au, ¹⁷²Yb(¹⁹F,5n)¹⁸⁶Au, and ¹⁵⁹Tb(²⁹Si,4n)¹⁸⁴Au reactions, respectively. The πi_13/2⊙νi_13/2 bands in these three nuclei have been identified and extended up to high-spin states. In particular, the inter-band connection between the πi_13/2⊙νi_13/2 band and the ground-state band in ¹⁸⁴Au has been established, leading to a firm spin-and-parity assignment for the πi_13/2⊙νi_13/2 band. The low-spin signature inversion is found in the πi_13/2⊙νi_13/2 bands according to our spin-assignment and the signature crossing observed at high-spin states.
