Abstract : Excited states in 212Po have been populated by α transfer using the 208Pb(18O,14C) reaction and studied with the Euroball γ multidetector array. Very enhanced E1 transitions have been revealed by very short lifetimes measured by the DSAM method, found in the [0.1-1.4] ps range. The emitting states, which have non-natural parity values, are the fingerprints of the "α-208Pb" structure present in 212Po.
