MEASUREMENT OF THE γ DECAY FROM THE ENERGY REGION OF THE PYGMY DIPOLE STATES EXCITED IN THE 208Pb(p,p'γ) REACTION AT CCB.

For a few years, the medical cyclotron Proteus C-235 at the Cyclotron Centre Bronowice in Kraków, Poland has been regularly used fornuclear structure experiments. One of the ongoing studies is focused on the γ decay of collective states populated in (p,p'γ) reactions. In a recent experiment, γ decays of excited states in the energy region of the Pygmy Dipole Statesin 208Pb have been observed. Good efficiency and energy resolution provided by the PARIS clusters and LaBr3Ce scintillators facilitate a comparison of the obtained energy spectra with previous measurements of pygmy states in this nucleus.
