论文摘要
提出了一种新的二维程序，用于推出在无核壳模型（NCSM）计算中获得的物质，中子和质子半径的值，提出了其基础的无限大小。半径之间的关系用作附加测试。连同RADII的NCSM计算中经常使用的JISP16电势，首次将Daejeon16电位用于这些目的。 Halo Nucleus 6HE是研究的对象。半径值的较小传播，使用这三个半径的值之间的关系成功测试，以及获得的结果与实验数据之间的合理一致性以及其他高级依次从头算计算的结果表明，开发方法的效率很高，因此，其应用的良好前景。对其他研究结果进行的研究和分析表明，6HE的光环具有较大的0.7-0.8 FM。
A new two-dimensional procedure for extrapolation of the values of matter, neutron, and proton radii obtained in no-core shell model (NCSM) calculations to infinite size of its basis is proposed. A relationship between the radii is used as an additional test. Together with the JISP16 potential, which is frequently used in NCSM calculations of the radii, the Daejeon16 potential is applied for these purposes for the first time. Halo nucleus 6He is the object of studies. The small spread of radii values, successful testing using relationship between the values of these three radii, and reasonable agreement between the obtained results and experimental data as well as the results of other advanced ab initio calculations demonstrate the high efficiency of the developed approach and, therefore, good prospects for its application. The performed investigations and analysis of the results of other studies indicate that the halo of 6He has a large size 0.7 - 0.8 fm.
