REFLECTIONS OF AN ATOM
Physicists have developed lenses and prisms to manipulate beams of
atoms and molecules as though they were beams of light. Now, in
the 21 July PRL, a team reports on their design and testing of an
atomic mirror. Before reflection, the system must put the atoms
into a highly excited state. Almost any atom or molecule can be
excited into one of these states, so the mirror along with other
components could lead to new experiments on the wave nature of
atoms, as well as improved devices like gyroscopes or atomic clocks,
researchers say.
