Because xenon is a tracer for two parent isotopes, xenon isotope ratios in meteorites are a powerful tool for studying the formation of the Solar System.The iodine–xenon method of dating gives the time elapsed between nucleosynthesis and the condensation of a solid object from the solar nebula. Reynolds discovered that certain meteorites contained an isotopic anomaly in the form of an overabundance of xenon-129.
The program, called IBM in atoms, used a scanning tunneling microscope to arrange 35 individual xenon atoms on a substrate of chilled crystal of nickel to spell out the three letter company initialism.Xenon is obtained commercially as a by-product of the separation of air into oxygen and nitrogen.After this separation, generally performed by fractional distillation in a double-column plant, the liquid oxygen produced will contain small quantities of krypton and xenon.In 1934, Edgerton was able to generate flashes as brief as one microsecond with this method. He tested the effects of varying the breathing mixtures on his subjects, and discovered that this caused the divers to perceive a change in depth.From his results, he deduced that xenon gas could serve as an anesthetic. Lazarev apparently studied xenon anesthesia in 1941, the first published report confirming xenon anesthesia was in 1946 by American medical researcher John H. Xenon was first used as a surgical anesthetic in 1951 by American anesthesiologist Stuart C.
