本文简单地估计了Δ共振对核中等矢量M1和Gamow-Teller矩的影响。核子-Δ跃迁和核子-核子跃迁的矩阵元比是基于夸克模型的。所观察到的M1矩和GT巨共振的能量产生一致的相互作用的强度值。
A simple estimate is made of the effect of the Δ resonance on isovector M1 and Gamow-Teller moments in nuclei. The ratio of matrix elements for nucleon-Δ to nucleon-nucleon transitions are based on the quark model. The observed M1 moments and energies of GT giant resonances yield consistent values for the strength of the interactions.
