论文摘要
基于相对论的介子 - 核子拉格朗日的核反应的显微镜理论应用于多种核系统中等构巨型单极共振（ISGMR）的描述。结果表明，在铅近似中，二颗粒振动耦合（QPVC）类型的无参数包含在铅，TIN，锆和镍质量区域中的ISGMR中同时对ISGMR的ISGMR进行了同时的现实描述，而在平均层面上很难。该计算采用有限范围有效的梅森核子相互作用，该相互作用与QPVC结合使用，始终证明了可靠地描述许多其他核结构现象的能力。等镍同位素的等尺度单极反应的系统计算有助于揭示ISGMR与低能四极杆态在ISGMR质心的位置中耦合的核心作用。
Microscopic theory of the nuclear response based on the relativistic meson-nucleon Lagrangian is applied to the description of the isoscalar giant monopole resonance (ISGMR) in a variety of nuclear systems. It is shown that the parameter-free inclusion of beyond-mean-field correlations of the quasiparticle-vibration coupling (qPVC) type in the leading approximation allows for a simultaneous realistic description of the ISGMR in nuclei of lead, tin, zirconium, and nickel mass regions, which is difficult on the mean-field level. The calculations employ the finite-range effective meson-nucleon interaction, which, in combination with the qPVC, has consistently demonstrated the ability to reliably describe many other nuclear structure phenomena. Systematic calculations of the isoscalar monopole response for nickel isotopes help reveal the central role of the coupling between the ISGMR and the low-energy quadrupole states in the placement of the ISGMR centroids.
