Abstract：
In the framework of the projected shell model, we investigate the competition between the two-quasineutron and two-quasiproton K^π=6⁺ states in the ytterbium isotopes and N=104 isotones adjacent to ¹⁷⁴Yb. The ¹⁷⁴Yb results are compared with the experimental data. The K^π=6⁺ isomer observed in ¹⁷⁴Yb is assigned as an admixture of the ν7/2^-[514]×ν5/2^-[512] and π7/2⁺[404]×π5/2⁺[402] intrinsic structure, which explains the experimental |g_K-g_R| value. Similar mixing would appear in ¹⁷²Yb, ¹⁷⁶Hf, and ¹⁷⁸W. The low-lying K^π=6⁺ states are also predicted in ^170-178Yb.
