In this contribution, we discuss recent results on the determination of the electric dipole polariz-ability αD for the neutron-rich isotope 22 O within the ab initio framework. Our calculations utilize the Lorentz integral transform coupled-cluster (LIT-CC) approach with two different chiral potentials that incorporate two-and three-nucleon interactions. We compare our predictions with the available experimental data and find good agreement in the low-energy region.
