Abstract
High-spin states in186Pt have been populated by the188Os (α, 6n) reaction and were investigated with the OSIRIS spectrometer. A shape coexistence at high spins was established in the nucleus186Pt, which lies on the border between light prolate and heavy oblate Pt nuclei. Two bands corresponding to predominantly prolate shapes and one band of predominantly oblate shape have been observed. For prolate shapes a (π h 9/2)2 alignment and for oblate shapesa (vi 13/2)2 alignment has been found.
