四核子破裂阈值以上的中子- ${}^3$ H散射

Neutron-${}^3$H scattering above the four-nucleon breakup threshold

A. Deltuva, A. C. Fonseca

摘要:

本文用Alt、Grassberger和Sandhas的四体方程求解了能量高于四核子破裂阈值的中子- ${}^3$ H散射。采用特殊权值积分的方法,大大提高了复能量法的精度和实用性。这允许获得具有真实核相互作用的完全收敛的结果。对现有的中子- ${}^3$ H弹性散射数据进行了满意的描述。

英文摘要:

The four-body equations of Alt, Grassberger and Sandhas are solved for the neutron-${}^3$H scattering at energies above the four-nucleon breakup threshold. The accuracy and practical applicability of the employed complex energy method is significantly improved by the use of integration with the special weights. This allows to obtain fully converged results with realistic nuclear interactions. A satisfactory description of the existing neutron-${}^3$H elastic scattering data is obtained.
