论文摘要
我们适应局部密度近似，以添加高弹药尾（HMTS），以有限核的Slater确定动量分布。 HMT通过扩展的Brueckner-Hartree-fock（EBHF）方法提取或最低阶群集近似。随着校正因子被添加到EBHF中，它与实验基准的一致，即高摩托姆$ n/z $比率大约等于$ 1 $，而低Momentum $ n/z $比率大约等于系统的$ n/z $。还发现，张量化力使核子核子相关性在核表面区域和高摩肌（$ p> 300 $ meV/c）核的百分比上更容易，约17美元\％$ - $ 18 \％$，独立于isospin的不对称。
We adapt the local density approximation to add the high-momentum tails (HMTs) to finite nuclei's Slater-determinant momentum distributions. The HMTs are extracted by the extended Brueckner-Hartree-Fock (EBHF) method or by the lowest order cluster approximation. With a correction factor being added to EBHF, it is sufficiently in agreement with the experimental benchmark, i.e., the high-momentum $N/Z$ ratios approximately equal to $1$, and the low-momentum $N/Z$ ratios approximately equal to $N/Z$ of the systems. It is also found that the tensor force makes the nucleon-nucleon correlations appear more easily on the nuclear surface region and the percentage of high-momentum ($p > 300$ MeV/c) nucleons, around $17\%$--$18\%$, independent of isospin asymmetry.
