Lire la suite >Ammonia microwave transitions between vibration-inversion states in the range 6300-7200 cm^(-1) are predicted with enhanced sensitivity coefficients to the variation of the proton-electron mass ratio. These transitions may be addressed by optical pumping and Ramsey interrogation scheme with a molecular fountain setup. A molecular clock based on a sensitive transition may provide 10^(-9) (t/1s)^(-1/2) level fractional stability and 10^(-15) level fractional accuracy, and may enable probing proton-electron mass ratio fractional variation at the 10(-13) level or better in hours of averaging time.Lire moins >
