Influence of heat treatment on target for hydrogen discharge experiment

In experiments of hydrogen discharge ,4 invariable-energy unknown X-ray lines were detected when TiT radioactive source bombarded background target. The unknown X-ray disappeared when TiT radioactive source bombarded heat treated background target, which proved that unknown X-ray lines were not emissions from impurities in the target. Two background targets of homogeneity material were made, one of which was heated, and then both were bombarded by the hydrogen discharge source to form the irradiated targets. TiT radioactive source bombarded the irradiated targets, and 4 unknown X-ray lines of the heat treated target were evident, which proves that heat treatment enhances adsorption capability of target.
