摘要：

We study the interplay between the isoscalar (T = 0) and isovector (T = 1) pairing correlations in N = Z odd-odd nuclei from N-14 to Cu-58 by using three-body model calculations. The spintriplet T = 0 pairing correlation dominates in the ground states of N-14, F-18, P-30, and Cu-58 with the spin-parity J(pi) = 1+, which can be well reproduced by the present calculations. The magnetic dipole and Gamow-Teller transitions are found to be strong in F-18 and Sc-42 as a manifestation of SU(4) symmetry in the spin-isospin space. We also discuss the spin-quadrupole transitions in these nuclei.
