Description of the shape evolution in the yrast states of 186Pt

¹⁸⁶Pt was tested in the framework of IBM-1 and the X(3) model. The results show that ¹⁸⁶Pt is located close to the shape phase transition point, but the B(E2) values little agree with the X(3) model. The shape evolution in the yrast states of ¹⁸⁶Pt is also discussed in detail. TRS calculation exhibits a flat bottomed potential at low spin states, but a relatively deep minimum at high spin states. It suggests that a shape evolution from vibrational mode to rotational mode happens in ¹⁸⁶Pt. The result is in agreement with the E-GOS calculation.
