论文摘要
通过显微镜自持续模型研究了巨大偶极共振（GDR）和$^{208} $ PB的巨型四极共振（GQR）的直接$γ$ - $^{208} $ PB的巨型四极共振（GQR）。该模型认为效果超出了线性响应近似。证明了$γ$ -DECAY的强烈敏感性证明了对所涉及州的同胞的敏感性。通过比较它们的衰减宽度，在GQR Wave Wave功能中的$ 2_ {1}^{1}^{1}^{1}^{+} $组件的重量中，推导了$^{208} $ pb的$ 3_ {1}^{ - } $组件的重量更大。因此，我们已经表明，$γ$ - 定期是共振波函数的独特探测，也是核结构模型的测试场。
The direct $γ$-decays of the giant dipole resonance (GDR) and the giant quadrupole resonance (GQR) of $^{208}$Pb to low-lying states are investigated by means of a microscopic self-consistent model. The model considers effects beyond the linear response approximation. The strong sensitivity of $γ$-decay to the isospin of the involved states is proven. By comparing their decay widths, a much larger weight of the $3_{1}^{-}$ component in the GQR wave function of $^{208}$Pb is deduced, with respect to the weight of the $2_{1}^{+}$ component in the GDR wave function. Thus, we have shown that $γ$-decay is a unique probe of the resonance wave functions, and a testground for nuclear structure models.
