CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe frequency of several hyperfine components of 127I2 has been measured at 514.67 nm using an optical frequency comb. Among them, the a3 component of the P(13)43-0 transition is recommended by the CIPM for the practical realization of the definition of the metre. The result is consistent with other measurements of the same line within 1.5 kHz of uncertainty, when the collisional shift is taken into account. A frequency-doubled distributed feedback fibre laser has been developed to carry out these measurements.
