研究了氘入射能量为4.7 ~ 18 keV时，金属Ti中的D+D反应。观察到的质子，tritons和3 He粒子发射的氘轰击在TiDx。首次测量了D（d，p）T和D（d，n）3 He反应在轰击能量分别降至4.7和5.4keV时的厚靶产额。用天体物理S因子对上述现象进行了很好的解释，S因子是由D（d，p）T反应的Ed>6 keV和D（d，n）3 He反应的Ed> 13.3keV的气体靶测量结果导出的。得到的截面比σ（d，p）/σ（d，n）低至6.4keV，并且发现当Ed <20 keV时，截面比σ（d，p）/σ（d，n）恒定在1.0左右。
The D+D reactions in Ti metal were investigated for the deuteron incident energies between 4.7 and 18 keV. Observed were protons, tritons and 3 He particles emitted in the deuteron bombardment on TiD x . Thick target yields for the D(d, p)T and D(d, n) 3 He reactions were measured at bombarding energies down to 4.7 and 5.4 keV, respectively, for the first time. They were well explained with the reported astrophysical S-factors which were deduced from gas target measurements at E d >6 keV for the D(d, p)T reaction and E d >13.3 keV for the D(d, n) 3 He reaction. The cross section ratio σ(d, p)/σ(d, n) was obtained down to 6.4 keV, and was found to be constant at around 1.0 for E d <20 keV.
