利用强流低能氘离子束轰击由吸氢金属形成的氘自吸收靶，研究固体内Ｄ－Ｄ聚变反应规律。并通过对实验测得的Ｄ－Ｄ聚变伴随粒子能谱，探索Ｄ－Ｄ聚变反应与靶材料结构的相关性。同时，利用氘团族离子（ｄ３＋）和氘核（ｄ＋）来轰击吸氘固体，研究固体内Ｄ－Ｄ聚变反应的特性。实验中观测到了伴随离子能谱中介于质子峰（３ＭｅＶ）和氚峰（１ＭｅＶ）之间的一个宽峰。结果分析表明。该峰是由固体靶内超出离子射程几倍至十几倍处发生的Ｄ－Ｄ聚变反应出射的质子所形成。同时还发现独立氘核产生的这种深部Ｄ－Ｄ核聚变的反应率高于速度相同的氘团簇离子中的氘核的反应率。
The deuterium self-absorption target formed by hydrogen-absorbing metal was bombarded with high-intensity low-energy deuterium ion beam to study the D-D fusion reaction rule in solid. The correlation between the D-D fusion reaction and the structure of the target material was explored by experimentally measuring the energy spectrum of the accompanying D-D fusion particles. At the same time, deuterium dodecyl ions (d3 +) and deuterons (d +) were used to bombard the sucked deuterium solid to study the characteristics of the D-D fusion reaction in the solid. In the experiment, a broad peak between the proton peak (3MeV) and the tritium peak (1MeV) was observed in the accompanying ion spectrum. Analysis of the results shows. This peak is formed by the proton exiting the D-D fusion reaction that occurs several times to ten times beyond the ion range within the solid target. It has also been found that the response rate of such deep D-D fusion produced by independent deuterons is higher than that of deuterons in deuterium cluster ions at the same speed.
