标题： Surface behaviour of the pairing gap in a slab of nuclear matter

摘要： 配对间隙的表面行为之前已在半无限核物质中进行过研究，现在在板状几何结构中进行了分析。 间隙形状函数在两种情况下计算：(a) 在硬墙势中使用Gogny力进行配对，(b) 在Saxon-Woods平均场势中使用可分离的Paris相互作用进行配对。 结果表明，在板状几何结构的情况下，表面特征得以保留，几乎与板的宽度无关。 还证明了当化学势的绝对值$|\mu|$减小时，表面增强效应会加强，这模拟了接近中子滴线的情况。 显示英文摘要

摘要： The surface behaviour of the pairing gap previously studied for semi-infinite nuclear matter is analyzed in the slab geometry. The gap-shape function is calculated in two cases: (a) pairing with the Gogny force in a hard-wall potential and (b) pairing with the separable Paris interaction in a Saxon-Woods mean-field potential. It is shown that the surface features are preserved in the case of slab geometry, being almost independent of the width of the slab. It is also demonstrated that the surface enhancement is strengthened as the absolute value of chemical potential $|\mu|$ decreases which simulates the approach to the nucleon drip line.
