Multiple Coulomb-excitation experiments for $$^{156}$$Gd were made with a 118 MeV $$^{32}$$S beam and a 225 MeV $$^{58}$$Ni beam. The ground-state band, the $$beta$$ band ($$K$$=0$$^{+}$$), and the $$gamma$$ band ($$K$$=2$$^{+}$$) were observed up to the 18$$^+$$, 14$$^+$$, and 12$$^+$$ states, respectively, while the octupole band ($$K$$=1$$^{-}$$) was observed up to the 15$$^-$$ state, through the analysis of particle-$$gamma$$-$$gamma$$ data. The intrinsic matrix elements entering the generalized intensity relations were obtained so as to reproduce the spin dependence of the $$E$$2 matrix elements extracted from the experimental results of particle-$$gamma$$ angular correlation for the transitions within each band and between each band and the ground-state band by the least-squares search code gosia. The change of characters in the $$beta$$ and $$gamma$$ bands is discussed as a possible cause for the variation of the $$E$$2 matrix elements in the higher-spin region.

The quadrupole shape evolution in heaviest stable Mo isotopes is studied in terms of the shape coexistence phenomenon occurrence in this region of nuclear chart. Quadrupole deformation parameters of the $$^{96,98,100}$$Mo isotopes in the low-lying (ground and excited) 0$$^+$$ states were deduced using Coulomb excitation method. In all cases rich sets of electromagnetic reduced matrix elements were determined using the GOSIA code and then analyzed using the Quadrupole Sum Rules formalism. Discussion of the experimental results in comparison with the predictions of microscopic calculations within the general quadrupole collective Bohr Hamiltonian model is presented for $$^{100}$$Mo.

The nuclei $$^{96}$$Mo and $$^{100}$$Mo have been Coulomb excited using various combinations of beams and targets. The investigation of the eletromagnetic structure of these isotopes provides an experimental background for a theoretical description of the shape coexistence observed in the previously studied $$^{98}$$Mo isotope.
