In the present investigations, 500eV to 10 keV D^+ ions were injected into 0.02 mm thick TiD_<1.93> foils at room temperature. The protons and toritons from the D (d, p) T as well as ^3He from the D (d, n) ^3He were monitored using a solid state detector with large solid angle. The possible fusion rate was determined over a period of 65h. The D-D reaction rate follow closely those obtained by extraporation of the Gamow function to low energies. During irradiation of 500eV D^+ ions, few counts from the D (d. p) T reactions were monitored, showing that the possible "cold fusion" reaction rate is smaller than the background count rate.

在本研究中，在室温下将500eV ~ 10kev的D^+离子注入0.02 mm厚的TiD_<1.93>薄膜中。用大立体角固态探测器监测了D (D, p) T和D (D, n) ^3He的质子和扭子。在65h内测定可能的融合速率。D-D反应速率与由伽莫夫函数向低能外推所得的反应速率基本一致。在500eV的D^+离子辐照过程中，很少监测到D (D . p) T反应的计数，表明可能的“冷聚变”反应速率小于本底计数速率。
