Abstract :
The absolute frequency of the hyperfine component a10 in the transition R(56)32-0 of iodine has been measured using the D2 line in Rb at 780 mm and an iodine-stabilized 633-nm He-Ne laser as references. This measurement provides a secondary frequency standard within the tuning range of a doubled Nd:YAG laser. The measured frequency of the a10 component is 563 260 223.480 MHz ±70 kHz
