摘　　要：测量了^(58),^(60),^(62),^(64)Ni(p,t_0)基态跃迁的角分布并与DWBA计算结果进行了比较。增强因子的相对值随中子数变化的关系与SU(5)极限下Ω_υ=11和Ω_υ=15时IBA预告的平均值很好地一致。Angular distributions of 53,60,62,64Ni(p, t) ground state transitions were measured and' compared with DWBA predictions. Relative enhancement factors for four Ni isotopes were given. Comparison between the relative enhancement factors and the predictions of the SU(5) limiting symmetries of IBA model showed that the experimental data were consi-sfent with the average values of Ωv = ll and Ωv = 15 transition intensities.
