Description

The highly-efficient and segmented TIGRESS HPGe γ array at TRIUMF permits accurate Coulomb-excitation studies of the high-lying 2+1 states found in light nuclei with even number of protons and neutrons. A Coulomb-excitation measurement of 20Ne projectiles at safe energies has been carried out with the 110Pd(20Ne,20Ne)110Pd reaction at 64.7 MeV. A larger reduced transition probability of B(E2; 2+1 to 0+1 ) = 26:5 plus or minus 1:7 W.u. has been determined in disagreement with the accepted value and mean-field calculations. This larger B(E2; 2+1 to 0+1 ) mitigates, however,previous discrepancies with the rotational model of Bohr and Mottelson.
