Abstract

The lifetimes of the 2⁺₁, the 2⁺₂ and the 3⁻₁ states of ²¹⁰Po have been measured in the ²⁰⁸Pb(¹²C,¹⁰Be)²¹⁰Po transfer reaction by the Doppler-shift attenuation method. The result for the lifetime of the 2⁺₁ state is about three times shorter than the adopted value. However, the new value still does not allow for a consistent description of the properties of the yrast 2⁺₁, 4⁺₁, 6⁺₁, and 8⁺₁ states of ²¹⁰Po in the framework of nuclear shell models. Quasi-particle Phonon Model (QPM) calculations also cannot overcome this problem thus indicating the existence of a peculiarity which is neglected in both theoretical approaches.
