    "abstract": "We study the isoscalar (T=0) and isovector (T=1) pairing correlations in N=Z\nnuclei. They are estimated from the double difference of binding energies for\nodd-odd N=Z nuclei and the odd-even mass difference for the neighboring\nodd-mass nuclei, respectively. The empirical and BCS calculations based on a\nT=0 and T=1 pairing model reproduce well the almost degeneracy of the lowest\nT=0 and T=1 states over a wide range of even-even and odd-odd N=Z nuclei. It is\nshown that this degeneracy is attributed to competition between the isoscalar\nand isovector pairing correlations in N=Z nuclei. The calculations give an\ninteresting prediction that the odd-odd N=Z nucleus 82Nb has possibly the\nground state with T=0.",
