用多普勒频移衰减法测量了~(208)Pb(12C，10Be)~(210)Po转移反应中~(210)Po的寿命、能级和态。态寿命的结果比采用的值短了大约三倍。然而，新的值仍然不允许在核壳模型的框架内一致地描述210Po的Yrast、、和态的性质。准粒子声子模型(QPM)的计算也不能克服这一问题，从而表明存在一个在两种理论方法中都被忽略的特性。
The lifetimes of the, theand thestates of210Po have been measured in the208Pb(12C,10Be)210Po transfer reaction by the Doppler-shift attenuation method. The result for the lifetime of thestate 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,,, andstates of210Po 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.
