Differential cross sections of deuteron–deuteron fusion reactions are needed in astrophysics, precision cosmology, nuclear physics, and controlled nuclear fusion research. New parametrizations for center of mass differential cross sections, total cross sections and astrophysical $S$-factors in a wide range of specific energy from 0.5 keV/u to about 0.5 GeV/u have been obtained. Straightforward approximating formulae readily suitable for multithreaded algorithmization are given here for ²H(d,n)³He and ²H(d,p)³H reactions. The energy range is about two orders of magnitude broader than that in the tables published earlier for neutron branch.

微分和总横截面以及天体物理 $\mathrm{小号}$宽能范围内² H（d，n）³ He和 ² H（d，p）³ H反应的影响因子 

在天体物理学，精密宇宙学，核物理和受控核聚变研究中，需要氘-氘核聚变反应的不同截面。质心微分横截面，总横截面和天体物理的新参数化$\mathrm{小号}$已经获得了从0.5keV / u到约0.5GeV / u的宽比能范围内的α-因子。对于² H（d，n）³ He和 ² H（d，p）³ H反应，此处给出了容易适用于多线程算法的直接近似公式。能量范围比先前针对中子支路发布的表格要宽两个数量级。
