Found in primitive meteorites diamond particles, is likely to be formed in the solar system before, so the hidden in the diamond particles of rare gases, has become one of the important clue to explore the early solar system formation, and these gases can enter the diamond particles, may and ion implantation, ion implantation) households lave.

The diamond particles found in the original meteorites are tiny, about 2.6 nanometers (nanometers), or about the size of 1,000 carbon atoms. Based on the noble gas (mainly xenon) contained in the diamond particles, it is speculated that the diamond particles may have come from the explosion of a supernova. When heated at different temperatures, meteorite diamond particles release different isotopic compounds, suggesting that these compounds have different sources.

How did these rare gases get into the meteorite diamonds? One theory is that the gas was captured as the diamond particles formed; But Koscheev etc are regarded as ion implantation, ion implantation) mechanism, they in the lab to nanoscale diamond (4 nm) is engaged in the experiment found that the injection of the same kind of isotope compound in nanoscale diamond to low temperature and high temperature heat release, the diamond particles and meteorite when heated, gases releasing peak temperature have two matches, as to the presence of different gases may be due to different time (or location) are caused by ion implantation situation happened.
