我们描述了一种改进通过加维-凯尔森迭代过程获得的核质量预测的过程。这是通过减少该过程中涉及的自由度、用一个中子和一个质子分离能来表达加维-凯尔森关系并对其进行理论估计来实现的。这种方法的效果是与迭代过程相关的内在误差增长得明显更慢。这可以提高核质量预测的质量，从而扩大预测的准确范围。我们使用不同的质量模型来测试这些想法。
We describe a procedure to improve the nuclear mass predictions obtained by means of the Garvey-Kelson iterative process. This is achieved by reducing the degrees of freedom involved in the process, expressing the Garvey-Kelson relations in terms of one-neutron and one-proton separation energies, and using a theoretical estimation for them. This approach has the effect that the intrinsic error associated with the iterative process grows significantly more slowly. This leads to a better quality of nuclear mass predictions and therefore extends the range for which the predictions are accurate. We test these ideas using different mass models.
