Abstract: Contrastive experiment of hydrogen gas discharge source bombarding targets has been done. The result of contrast between hydrogen gas discharge source bombarding new and used targets ensures that a kind of anomalous particles have been produced through hydrogen gas discharge and it is proved that new spectral lines have been eradiated when X-ray or particle beam bombarding the anomalous particles. It is concluded that the new spectral lines are energy level lines of anomalous particles and domonstrate the anomalous particle’s energy level characteristics. The new spectral lines are the sign of anomalous particles.
