摘要:

裸核子-核子相互作用是产生原子核中的对关联的必要条件,但一个重要的贡献也来自于在接近费米能的时间反演态中运动的核子之间的集体振动交换所产生的诱导相互作用。由相加相互作用产生的对场在核表面有很强的峰值。它是可能的,以重现详细的空间依赖性,这个字段使用局部密度近似(LDA)和接触相互作用,与参数,这是非常不同的那些常用的现象学的方法。

英文摘要:

The bare nucleon-nucleon interaction is essential for the production of pair correlations in nuclei, but an important contribution also arises from the induced interaction resulting from the exchange of collective vibrations between nucleons moving in time reversal states close to the Fermi energy. The pairing field resulting from the summed interaction is strongly peaked at the nuclear surface. It is possible to reproduce the detailed spatial dependence of this field using a Local Density Approximation (LDA) and a contact interaction, with parameters which are quite different from those commonly used in more phenomenological approaches.
