... of the fundamental constants of nature by boosting an electron to an orbit as far as possible from the atomic nucleus that binds it. The experiment, outlined in a new paper,* would not only mean more ...
... of the most sensitive instruments ever built, able to detect motions smaller than the size of an atomic nucleus," said Tanner. "It's very interesting that even with such a sensitive instrument, we ...
