We present the first Gogny-Hartree-Fock-Bogoliubov (HFB) model which reproduces nuclear masses with an accuracy comparable with the best mass formulas. In contrast with the Skyrme-HFB nuclear-mass models, an explicit and self-consistent account of all the quadrupole correlation energies are included within the 5D collective Hamiltonian approach. The final rms deviation with respect to the 2149 measured masses is 798 keV. In addition, the new Gogny force is shown to predict nuclear and neutron matter properties in agreement with microscopic calculations based on realistic two- and three-body forces.
我们展示了首个Gogny-哈特里-福克-博戈留波夫（HFB）模型，该模型再现核质量的精度可与最佳质量公式相媲美。与斯凯瑞HFB核质量模型不同，在五维集体哈密顿方法中包含了对所有四极关联能的明确且自洽的描述。相对于2149个测量质量的最终均方根偏差为798千电子伏特。此外，新的Gogny力被证明能够预测核物质和中子物质的性质，与基于现实两体和三体作用力的微观计算结果相符。
