补充资料:同位旋
同位旋 isospin 反映自旋和宇称相同、质量相近而电荷数不同的几种粒子归属性质的量子数。粒子的性质之一。实验表明,核力具有电荷无关性,质子和质子、中子和中子及质子和中子之间的核力是相同的,这说明就核力的性质而言,质子与中子之间没有区别,因此把质子和中子看成同一种粒子的两种不同状态,类比自旋的概念引入抽象的同位旋空间,质子和中子是同位旋I相同,同位旋第3分量I3不同的两种状态,由此可确定它们的同位旋I=1/2,质子的I3=1/2,中子的I3=-1/2,它们组成同位旋二重态,它们质量上的微小差异来自I3的不同,犹如自旋取向不同引起自旋-轨道耦合的微小能量差异。同样Σ±、Σ0组成同位旋三重态,它们的同位旋I=1,同位旋第三分量I3分别为±1和0。原子核的同位旋可由质子和中子的同位旋“合成”得到,强子的同位旋由组成强子的夸克的同位旋“合成”得到。强相互作用下系统的同位旋和同位旋第三分量均守恒。 |
