核接触形式主义--氘核通道

The Nuclear Contact Formalism - the Deuteron Channel

Ronen Weiss, Nir Barnea

摘要:

接触形式主义,旨在阐明短程相关的重要作用,最近被推广到系统的耦合通道,如氘核通道,其中s和d波耦合成一个$J=1$状态。两个通道的耦合意味着两个独立的渐近解,并产生2x2的接触矩阵。对于强耦合,在适当的边界条件下,如在核物理中,两个解退化为单个渐近波函数。在这里,我们探索的相关中子质子对在氘核通道的渐近行为使用示意性模型和现实的核力。

英文摘要:

The contact formalism, devised to elucidate the important role of short-range correlations, was recently generalized for systems with coupled channels, such as the deuteron channel, where s and d waves are coupled into a $J=1$ state. The coupling of the two channels implies two independent asymptotic solutions and results a 2x2 contact matrix. For a strong coupling, with appropriate boundary conditions, such as in nuclear physics, the two solutions degenerate into a single asymptotic wave function. Here, we explore the asymptotic behavior of the correlated neutron-proton pairs in the deuteron channel using both schematic models and realistic nuclear forces.
