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