Core polarizability of rubidium using spectroscopy of

2020-12-22 · We present a precise measurement of the rubidium ionic core polarizability. The results can be useful for interpreting experiments such as parity violation or black-body radiation shifts in atomic clocks since the ionic core electrons contribute significantly to the total electrical polarizability of rubidium.

RUBIDIUM ATOMIC CLOCK WITH DRIFT COMPENSATION

2011-10-19 · This paper shows the results of an automatic system that compensates drifts of rubidium atomic clocks, comparing to GPS. This leads to high stability in large time and low noise in short time. Introduction Rubidium atomic clocks are not primary standards because their frequencies change in time due to internal and external influence sources.
