In the present work, the low-lying 0+ states of the 170Yb isotope have been studied in order to explore what nuclear forces underlie the observed energy spectrum and its collective properties. Particularly, how basic trends in these data are correlated with the nuclear forces in our model Hamiltonian has been investigated. In this direction, a model Hamiltonian in which the spin-quadrupole force is introduced simultaneously with monopole pairing and quadrupole-quadrupole interactions has been used. To investigate the nature of these states, particular attention has been devoted to the two-nucleon transfer spectroscopic factors relative to the transition to the ground state and comparison of their calculated cumulative values with the experimental data. To expose the influence of the choice of the deformation parameters on the results, the calculations have been performed for two different quadrupole deformations. The results implied that a reasonable description for the distribution of the energies, the two-nucleon transfer spectroscopic factors and their cumulative values has been obtained in the framework of the present model. In addition, to point out the influence of the spin-quadrupole interaction on the excited 0+ states in 170Yb, the calculations have been repeated using the pairing plus quadrupole model.
