摘　　要：引出氢(氘)气放电产生的射线和粒子流打在非晶聚氘乙烯C2D4和有机玻璃C5H8O2等靶上,测得其散射谱上有多条尖锐的X谱线,其中除一条外都是(不经散射的)原始谱中没有的。经反复证认,这些谱线不是靶中元素(如C或O)和可能包含的杂质元素的特征X射线,也不是原始谱中X射线的衍射线,更不可能是低能电子的轫致辐射经吸收后形成的峰,认为该谱线很可能是前所未知的一类新的原子态的X射线新谱系的一部分。用曾提出的一个“小氢原子”理论模型予以解释,即认为氢(氘)气放电中产生了“小氢原子”,其(在基态)电子轨道半径约为普通氢原子的玻尔半径的1/274,该小氢原子能级之间的跃迁能够很好地解释所测到的X射线新谱系。Hydrogen （deuterium） gas discharge source was used to bombard target of non-crystalloid deuterate polyethylene polymethylmethacrylate, etc. The scattering spectrum was measured. There are several sharp X-ray spectral lines on the scattering spectrum, but the primary spectrum of the discharge does not include these lines of the scattering spectrum. It is confirmed that they are neither the characteristic X-ray of C, O or other possible impurity element, nor diffractive spectral lines, nor the “absorption cut off” of electron bremsstrahlung spectrum. It is most likely that they are a kind of X-ray spectral series of new kind of atom state. A new theory model called small hydrogen atom was put forward to explain the spectrum. It assumes that the discharge of hydrogen gas will produce small hydrogen atoms. The radius of the electron orbit of the atom is about aB/274 （aB is Bohr radius）. The transition between energy levels of small hydrogen atom matches up the X-ray spectrum.
