High-spin states in $$^{187}$$Pt has been studied experimentally by in-beam $$gamma$$-ray spectroscopy. The previously known bands based on the $$nu i_{13/2}, nu 7/2^{-}[503] $$ and $$nu i^{2}_{13/2} nu j$$ configurations have been extended to high-spin states, and new rotational bands associated with the $$nu 3/2^{-}[512]$$ and $$nu 1/2^{-}[521]$$ Nilsson orbits have been identified. The total Routhian surface calculations indicate that the transitional nucleus $$^{187}$$Pt is very soft with respect to $$beta$$ and $$gamma$$ deformations. The band properties have been compared with the systematics observed in neiboring nuclei and have been interpreted within the framework of the cranked shell model.
