Properties of excited states in 102Pd

Excited states of 102Pd, have been populated via inelastic proton scattering and Coulomb excitation with 160. The authors used pγ angular correlation measurements to construct a level scheme and to assign angular momenta, γ-ray multipolarities, and B(E2) ratios. Several new levels up to an excitation energy of 3 MeV have been observed, including a level at 1658 keV which is interpreted as the missing 0+ state of the two-phonon triplet. The 2+' → 2+, 2+'' 2+ and 3+ → 2+ transitions of 978, 1388 and 1556 keV were found to be essentially pure quadrupole radiations. The Coulomb excitation work yields B(E2, 0+ → 2+) = 0.46+-0.03e2 .b2 and an estimate for the static quadrupole moment of the first 2+ state of -0.2+-0.2e.b. (Auth.)
