论文摘要
我们已经研究了异基质和异位方质心能量的测量值ECEN的测量值，其巨大共振在44CA，54fe，64,68zn和56,58,60,60,68ni中具有多极性L = 0-3。为此，我们用33种不同的Skyrme型有效核素核子相互作用进行了球形Hartree-fock（HF）基于球形Hartree（HF）的随机相位近似（RPA）理论的计算。我们还确定了计算出的质心能量与每种相互作用相关的各种核物质（NM）特性之间的Pearson线性相关系数，并确定了ECEN对NM特性的敏感性。我们将巨型共振的计算出的质心能与实验数据进行了讨论，并讨论了结果。我们特别注意到，我们在ISOVECTOR巨型偶极子共振的计算出的ECEN与可用的实验数据之间获得了良好的一致性。
We have studied the uncharacteristic behavior of the measured values of the isoscalar and isovector centroid energies, ECEN, of giant resonances with multipolarity L=0-3 in 44Ca, 54Fe, 64,68Zn and 56,58,60,68Ni. For this purpose, we carried out calculations of ECEN within the spherical Hartree-Fock (HF)-based random phase approximation (RPA) theory with 33 different Skyrme-type effective nucleon-nucleon interactions. We have also determined the Pearson linear correlation coefficients between the calculated centroid energies and the various nuclear matter (NM) properties associated with each interaction and determined the sensitivity of ECEN to NM properties. We compared the calculated centroid energies of the giant resonances with experimental data and discuss the results. We note in particular, that we obtain good agreement between the calculated ECEN of isovector giant dipole resonance and the available experimental data.
