The study of thermonuclear reactions such as D(d, p)³H, D(d, n)³He, T(d, n)³He, ³He(d, p)⁴He, and D(³He, p)⁴He is of great interest in the field of astrophysics, as it affects the primordial nucleosynthesis, as well as issues of stellar dynamics. These reactions are also of interest in thermonuclear power engineering, in connection with the increased interest in the possibility of practical application of thermonuclear fusion. In this work, the analysis of the results obtained in the course of studying the reaction D(³He, p)⁴He was carried out. The results were obtained by us in previous works on deuterated metal targets ZrD and TiD with Miller indices [111] and [100]. There is a need to more precise study of the effects accompanying thermonuclear reactions at low astrophysical energies. The purpose of this work is to study the behavior of the screening potential Ue and the reaction enhancement factor f(E), depending on the crystal structure of targets and the interaction energy. The studies were carried out on a Hall accelerator (Tomsk, TPU) in the energy range E(3He) = 16 − 34keV in lab reference frame with a step of 2keV. Experiments have shown that in reactions using metal deuterated targets a similar effect as in reactions using gas targets was observed. Specifically, an electron screening effect was observed, which leads to an increase in the reaction cross-section with decreasing energy, and in case of metal target this effect becomes stronger.

氘化金属靶材 TiD 和 ZrD 研究 D (3He, p)4He 反应中的增强因子和电子势

研究D(d, p) ³ H, D(d, n) ³ He, T(d, n) ³ He, ³ He(d, p) ⁴ He, and D( ³ He, p) ⁴他对天体物理学领域非常感兴趣，因为它影响原始核合成以及恒星动力学问题。这些反应在热核动力工程中也引起了人们对热核聚变实际应用可能性的兴趣的增加。在这项工作中，分析了在研究反应 D( ³ He, p) ^{4过程中获得的结果}他被抬出去了。我们在之前的研究中使用米勒指数 [111] 和 [100] 对氘代金属靶材 ZrD 和 TiD 获得了结果。需要更精确地研究在低天体物理能量下伴随热核反应的影响。这项工作的目的是研究筛选潜力的行为üe和反应增强因子F(乙)，取决于目标的晶体结构和相互作用能。这些研究是在能量范围内的霍尔加速器（托木斯克，TPU）上进行的乙(3他) = 16 - 34keV 在实验室参考框架中，步长为 2keV。实验表明，在使用金属氘化靶的反应中，观察到与使用气体靶的反应类似的效果。具体而言，观察到电子屏蔽效应，这导致反应截面随着能量的降低而增加，并且在金属靶的情况下，这种效应变得更强。
