用DBHF近似研究有限核的性能

Properties of Finite Nuclei Studied in DBHF Approximation

用DBHF近似计算了有限核的性能.作为例子,使用核子之间相互作用的单玻色子交换模型的最新方案研究了^(16)O的基态性质.Dirac效应大大增加了电荷分布半径,同时对结合能也有一定的改进,这个改进与实验数据符合得较好,但不能完全消除理论和实验的误差。

In this paper, the DBHF approximation is extended to the calculation of finite nuclei. As an example ,the ground-state properties of 0 are studied using modern versions of the one-boson-exchange model in the nucleon-nucleon interaction. The Dirac effect yields a significant increase for the radius of the charge distribution and a moderate gain in binding energy. This improves the agreement with the experimental data considerably, but does not remove the discrepancy between theory and experiment completely.
