Recommended values of standard frequencies - More information

The CIPM has charged the CCL-CCTF Frequency Standards Working Group (CCL-CCTF-WGFS) with maintaining this list of recommended values of standard frequencies for applications including the practical realization of the definition of the metre and secondary representations of the definition of the second.

info - m - fr

Toutes les radiations de cette liste (à l'exception de la transition de 87Rb 6,8 GHz) peuvent être utilisées pour réaliser le mètre.

info - s - fr

Les radiations accompagnées de [SRS] peuvent être utilisées comme représentations secondaires de la seconde.
