The nuclear properties of the Ytterbium isotopes and their evolution as the neutron number increases has been a central objective in this work. The medium-to-heavy mass Yb isotopes are known to be well-deformed rotational nuclei which can be populated to very high spins. Spectroscopic information becomes scarcer for neutron-rich nuclei, impeding the understanding of nuclear structure in this mass region, where interesting phenomena, such as shape coexistence [1], have been predicted to exist.

... e collective behavior of the even-even 164−180 70 Yb isotopes was investigated using several well-established theoretical models in synergy with available experimental data. In this work, reduced transition probabilities 𝐵(𝐸2) and transition quadrupole moments 𝑄 for even-even 164−178 70 Yb isotopes have been calculated using the Interacting Boson Model(IBM-1).
