Anomalous gamma emission with peak energy in spectrum of 57-180 keV was rarely observed during DC glow discharge for 30-90 minutes in 〜3Torr deuterium gas using deuterated palladium foil cathode. Autoradiography after the discharge experiment showed isotopes with low and high energy radiation components were produced before or during the discharge. The palladium foil after DC glow discharge was analyzed by secondary ion mass spectroscopy which reveal considerably increase in the content of Boron, Nickel. Silicon. sodium (Na), aluminum, calcium, magnesium, manganese, iron, copper and chromium on the surface.The controlled out-diffusion method was employed to induce a nuclear reaction in a palladium (Pd) plate with a MnOx film. The time-resolved mass spectra for Pd deuteride revealed tritium (T) production of molecules with mass number 4, which can be D_2, HT or helium during the out-diffusion experiment. Film blackening was observed for most Pd using a normal monochromatic negative photographic film. The radiation from the Pd plate consists of two kinds of components, which may be beta ray and X-ray. Secondary ion mass spectroscopy has shown considerable increase in counts of Li, , sodium (Na), potassium (K) after the out-diffusion experiment. All the results give credence to the suggestion that nuclear reactions possibly occur in the narrow near-surface layer.

实验放电后使用氘化钯箔阴极进行直流辉光放电 30-90 分钟，很少观察到光谱峰值能量为 57-180 keV 的异常伽马发射，显示同位素具有低能和高能辐射成分。通过二次离子质谱分析直流辉光放电后产生的钯箔，结果显示硼含量显着增加，镍、硅、铝、钙、镁、锰、铁、铜和铬。采用受控外扩散方法在具有 MnOx 薄膜的钯 (Pd) 板上引发核反应。氘化钯的时间分辨质谱显示，在外扩散薄膜过程中，产生了质量数为 4 的氚 (T) 分子，这些分子可以是 D_2、HT 或氦气。使用普通的单色负片胶片观察到大多数 Pd 变黑，来自 Pd 板的辐射由两种成分组成，可能是 β 射线和 X 射线，表明 Li 的数量显着增加。外扩散实验后的钠（Na）、钾（K） 所有结果都证实了核反应可能发生在狭窄的近地表层中。
