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.
