分别用单胶子交换和单π介子交换产生的夸克超精细相互作用,计算了最低质量负宇称核子态中的混合角.结果表明,两种交换之间的差别较大,混合角的实验数据更倾向于支持单胶子交换.
分彆用單膠子交換和單π介子交換產生的誇剋超精細相互作用,計算瞭最低質量負宇稱覈子態中的混閤角.結果錶明,兩種交換之間的差彆較大,混閤角的實驗數據更傾嚮于支持單膠子交換.

The mixing angles in the lowest mass negative parity nucleons are calculated by using the interquark hyperfine interactions which are induced by one gluon exchange and one pion exchange respectively. It is found that the difference is large between two kinds of exchanges, and the experimental data on such mixing angles favor one gluon exchange clearly.
