摘要

Researchers have, for the first time, captured radium atoms in a magneto-optical trap, laying the groundwork for a fundamental test of time's properties. Jeffrey Guest and a team at Argonne National Laboratory in Illinois trapped radium-225 and radium-226 atoms by cooling them with a combination of lasers and magnetic coils. The team was aided by the ubiquitous thermal radiation from their room-temperature apparatus, which helped to confine the atoms.
