Invisible helium atoms provide exquisitely sensitive test of fundamental theory - Science Daily

Physicists have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule -- or 10-35 joule), and used it to validate one of the most tested theories in physics -- quantum electrodyn…

Physicists at the Australian National University have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule -- or 10-3… [+3783 chars]
