<p>An atomic reflection optical element for an atomic wave (de Broglie wave) so constituted as to increase the reflectance of an atomic wave by reducing the apparent atomic density of a reflection plane; for example, a porous surface structure, a structure supporting a very thin film, or a structure in which the insular portion (reflection surface) of a reflection-diffraction grating is narrowed is used for this purpose. The above arrangement can provide an atomic reflection optical element having a high atomic wave coherent reflection power.</p> |
