Description
Experiment 23.054 was proposed to clarify the possible shape coexistence in the nucleus 106Pd. Around the Z=50 shell closure, shape coexistence has been firmly established in several isotopic chains, particularly in the tin and cadmium isotopes. Intruder states have also been identified in the palladium isotopes. Nevertheless, the coexistence of different shapes has not yet been unambiguously established in these nuclei. Recent results from our group suggested a different shape for the first excited 0+ state compared to the ground state in 106Pd, based on E0 transition measurements. Obtaining detailed information on the quadrupole shape of the states in this isotope is, therefore, extremely timely.
A Coulomb-excitation experiment was carried out at the INFN-LNL laboratory with the AGATA-SPIDER setup to investigate the quadrupole collectivity of 106Pd. The analysis is still ongoing; significant effort has been devoted to optimizing the spectral resolution in order to disentangle the numerous doublets present. Preliminary spectra with the best resolution currently achieved will be presented.
