SENSITIVITY OF THE NUCLEAR COLLECTIVITY TO THE PAIRING STRENGTH IN 150Nd

The sensitivity of the nuclear collectivity to the pairing strength in Nd-150 has been investigated in a collective Hamiltonian based on the relativistic point-coupling energy functional with the delta-pairing force. With the increasing pairing strength, the potential energy curve becomes shallower and softer, and the inertia parameters will be reduced rapidly. Correspondingly, the excited energies increase parabolically, but the characteristic collective observables, E(4(1)(+))/E(2(1)(+)) and B(E2 : 2(1)(+) -> 0(1)(+)) transition decrease linearly.
