Abstract

We present the results from an experiment dedicated to measure the lifetime of the 22+ state, candidate for the one-phonon mixed-symmetry state, of 208Po. This nucleus was studied in the α-transfer reaction 204Pb(12C,8Be)208Po and the lifetime of the 22+ state was determined by utilizing the Doppler-shift attenuation method. The experimental data show that the 22+ state decays with a sizable M1 transition to the 21+ state revealing its isovector nature.
