摘要Pairing from different fermions, neutrons and protons, is unique in nuclear physics. The fingerprint for the isoscalar T = 0 neutron-proton (np) pairing has however remained a question. We study this exotic pairing mode in excited states of rotating N approximate to Z nuclei by applying the state-of-the-art shell-model calculations for Ru-88 and the neighboring Ru-90,Ru-92 isotopes. We show that the T = 0 np pairing is responsible for the distinct rotational behavior between the N = Z and N > Z nuclei. Our calculation suggests a gradual crossover from states with mixed T =1 and T = 0 pairing near the ground state to those dominated by the T = 0 np pairing at high spins. It is found that the T = 0 np pairing plays an important role in enhancing the high-spin collectivity, thereby reducing shape variations along the N = Z line. (C) 2016 Elsevier B.V.
