摘要

利用马尔可夫链蒙特卡罗方法和Tikhonov正则化对中子-质子剩余相互作用能\(\Delta_{np}\)值的贝叶斯估计。这些估计值用于计算\(A>20\)的核质量表。通过与AME2020和其他理论核质量模型的实验数据进行比较，对预测结果的准确性进行了评价。

Nuclear Mass Model Based on Bayesian Estimate of Local Difference Experssions of Binding Energies

The Bayesian estimates of the value of the residual neutron–proton interaction energy \(\Delta_{np}\) using the Markov chain Monte Carlo method and Tikhonov regularization. These estimates are used for calculation of the nuclear mass table for \(A>20\). The accuracy of the obtained predictions is evaluated by comparison with experimental data from AME2020 and other theoretical nuclear mass models.

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
