This produces a stable, minimum energy configuration in which the outer electrons are tightly bound.It is also found as a component of gases emitted from some mineral springs.The nuclear spins can be aligned beyond ordinary polarization levels by means of circularly polarized light and rubidium vapor.The resulting spin polarization of xenon nuclei can surpass 50% of its maximum possible value, greatly exceeding the thermal equilibrium value dictated by paramagnetic statistics (typically 0.001% of the maximum value at room temperature, even in the strongest magnets).Elements more massive than iron-56 consume energy through fusion, and the synthesis of xenon represents no energy gain for a star.

Solid xenon changes from face-centered cubic (fcc) to hexagonal close packed (hcp) crystal phase under pressure and begins to turn metallic at about 140 GPa, with no noticeable volume change in the hcp phase. When metallized, xenon appears sky blue because it absorbs red light and transmits other visible frequencies.

By additional fractional distillation, the liquid oxygen may be enriched to contain 0.1–0.2% of a krypton/xenon mixture, which is extracted either by absorption onto silica gel or by distillation.

Finally, the krypton/xenon mixture may be separated into krypton and xenon by further distillation.

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.

Such non-equilibrium alignment of spins is a temporary condition, and is called hyperpolarization.
