摘要:

本文用含高斯项和零程项的简单密度相关有限程有效相互作用分析了对称和非对称核物质中平均场的动量和密度依赖性。在发展的形式主义,它是可能的再现各种不同的预测的动量和密度依赖的isovector部分的平均场在不对称的物质。在准局域密度泛函理论的框架下,给出了简单高斯相互作用下有限核的计算公式。球核相互作用的能量和电荷半径的预测与其他有效理论的结果进行了比较。

英文摘要:

The momentum and density dependence of mean fields in symmetric and asymmetric nuclear matter are analysed using the simple density dependent finite range effective interaction containing a single Gaussian term alongwith the zero-range terms. Within the formalism developed, it is possible to reproduce the various diverging predictions on the momentum and density dependence of isovector part of the mean field in asymmetric matter. The finite nucleus calculation is formulated for the simple Gaussian interaction in the framework of quasilocal density functional theory. The prediction of energies and charge radii of the interaction for the spherical nuclei compares well with the results of other effective theories.
