Electric monopole transitions and low-lying level structure in 106Pd

The structure of 106Pd, populated in the EC/beta+ decay of 106Ag, was investigated at the INFN Legnaro National Laboratories using the Spes Low-energy Internal Conversion Electron Spectrometer (SLICES). The K-internal conversion coefficients of some transitions have been measured and the electric monopole transition strengths, between low-lying 2+ and 0+ states, have been deduced. These experimental data combined with the results from internal conversion electron measurement on 104Pd previously performed by the Florence spectroscopy group were compared with the theoretical values calculated in the framework of the interacting proton-neutron boson model. Good agreement between experimental and theoretical values is found when interpreting the 0+3 level as an intruder state.
