摘要:

本文用Epelbaum \emph{et al.}新近发展的手征核子-核子势($NN$)研究了双核子束缚态和散射态。用手征$NN$势(N $^3$ LO)计算了氘的np微分截面和结合能.基于此螺旋度表示所获得的结果进行了比较,标准的分波(PW)的结果。这一比较表明,三维方法提供了相同的精度在描述的$NN$观测值和结果是在密切的协议与现有的实验数据。

英文摘要:

The recently developed chiral nucleon-nucleon ($NN$) potential by Epelbaum \emph{et al.} has been employed to study the two-nucleon bound and scattering states. Chiral $NN$ potential up to next-to-next-to-next-to leading order (N$^3$LO) is used to calculated the np differential cross section and deuteron binding energy in a realistic three dimensional approach. The obtained results based on this helicity representation are compared to the standard partial wave (PW) results. This comparison shows that the 3D approach provides the same accuracy in the description of $NN$ observables and the results are in close agreement with available experimental data.
