Abstract
It is known that the moment of inertia (MoI) for the collective rotation is strongly influenced by the pairing correlation. The ground-state MoI is investigated for about 1700 even-even nuclei from the proton drip line to the neutron drip line up to Z = 120 and N = 184 to discuss the pairing properties in exotic nuclei. To this end, the cranked Skyrme-Hartree-Fock-Bogoliubov equation is solved in the coordinate space. This model describes well the available experimental data of more than 300 nuclides possessing an appreciable deformation. I find that the predicted MoI near the drip line depend on the choice of the pairing functional having different density dependence. A systematic measurement of the excitation energy and the transition probability to the first Iπ = 2+ state in neutron-rich nuclei can constrain the density dependence of the pairing functional.
