摘要：

The Doppler broadening of the very narrow 6.4 MeV 1H(15N, αγ)12C resonant nuclear reaction is discussed and surveyed with respect to the behavior of hydrogen atoms adsorbed on tungsten crystal surfaces. For the (001) surface, the thermal vibration energy of the hydrogen atoms is definitely obtained. However, for the (110) surface, the resonance line shape is much wider than would be expected by the Doppler broadening contribution alone. This result may suggest that the stable site of the adsorbed hydrogen is not only on the surface but also inside the crystal. © 1990.
