Metallic hydrogen observed for the first time

摘要

Using a synchrotron,a team of researchers have observed hydrogen in its metal phase for the first time.Thcexistcnceof metal-phase hydrogen was predicted more than 80 years ago,sparking a race to observe it.While there have been many claims of proof in recent years,none have managed to convince the scientific community.Now a French team working at the SOLF.Il.synchrotron facility have published a paper in Nature suggesting they have done just mat.The team report that the development of a new kind of diamond anvil cell thai can exert over 4 million times the Earth's atmospheric pressure,togedier with the non-intrusive measurement of die insulator-metal transformation using very bright infrared radiation produced by the synchrotron allowed the researchers to observe the transition to the metallic phase.
