- Characterization of the Main Frequency Shifts for the Brazilian 133Cs Atomic Beam Frequency Standard A. Bebeachibuli M. S. Santos D. V. Magalhães S. T. Müller V.S. Bagnato Física, Astronomía y Matemáticas In order to evaluate an atomic clock, it is important to determine the main frequency shifts caused by externalfields, device imperfections, etc. Scanning the frequency of the main oscillator, the Ramsey fringe is obtainedand used to determine the main shifts. The gravitational shift (10¡17), second order Doppler (1.65£10¡13),Black-Body radiation shift (2.9£10¡14), quadratic Zeeman effect (5£10¡13), Rabi Pulling (1.3£10¡13) andcavity pulling (1.3£10¡13) have been evaluated. The short term stability, (6.6§0;2)£10¡13; was obtained. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435617 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.35
