Abstract

Atomic frequency standards realize the measurement of the atomic transition frequency between two well-defined quantum energy levels. This study uses the Euler–Cromer method to numerically analyse the atomic transition probabilities for the caesium fountain clock, based on the Ramsey method of separate fields. Consequently, this examination successfully attains an optimal compromise correlation among the oscillating field (BO), static field (BZ), and detuning (δw). Thus, this work presents a new tool for time and frequency metrology standardization.
