4496Ru+4496Ru and 4096Zr+4096Zr collisions at sNN=200 GeV provide unique opportunities to study the geometry and fluctuations raised from the deformation of the colliding nuclei. Using iEBE-VISHNU hybrid model, we predict ac2{3} ratios between these two collision systems and demonstrate that the ratios of ac2{3}, as well as the ratios of the involving flow harmonics and event-plane correlations, are sensitive to quadrupole and octupole deformations, which could provide strong constrains on the shape differences between 96Ru and 96Zr. We also study the nonlinear response coefficients χ4,22, which show insensitivity to the deformation effect.
