使用π介子和rho-介子交换势研究了Δ空穴激发在猝灭Gamow-Teller矩阵元中的效果。发现贡献小于使用 g'Δ= 0.6 的 Landau-Migdal 型相互作用计算得出的贡献。发现差异是由于 g'Δ 的选择造成的。讨论了普遍性g'N=g'Δ的有效性以及g'Δ的估计。
The effect of the Δ-hole excitation in quenching the Gamow-Teller matrix element is investigated using the pion and rho-meson exchange potential. The contributions are found to be smaller than those given by the calculation using the Landau-Migdal type interaction with g'Δ= 0.6. The difference is found to be due to the choice of g'Δ. Discussions concerning the validity of the universality g'N= g'Δand the estimate of g'Δare given.
