The lifetimes of the 
, the 
and the 
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 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 , 
, 
, and 
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.
