  atomic oscillator
The hyperfine structure of gas atoms and a system of atomic oscillator levels in a magnetic trap are considered as examples of such a quantum system.
      
Spontaneous emission from an atomic oscillator located near an ideally conducting conical surface
      
We consider the dynamics of the center-of-mass of an ultracold excited atomic oscillator in the vicinity of a dielectric microsphere.
      
The frequency shift and linewidth variation of an atomic oscillator placed next to a prolate dielectric or metal spheroid are found within the framework of the classical approach.
      
The similarities and differences between this type of theory and that of quantum mechanics are discussed with regard to the predictions about the lifetimes of excited atomic oscillator states.

It is well known that atomic hydrogen oscillator (or maser) is characterized by excellent frequency stability.However,it delivers a signal with power level of the order of 10-13W and a frequency of 1420.405 MHz,that is not practical for the users,and its output signal,in general,cannot be used directly.Therefore quartz-crystal oscilltor at a basic frequency has to be used and phase-locked to the hydrogen signal.This approach is shown in Fig.1.It is necessary to include a sensitive receiver and frequency synthesizer,thus,the...

It is well known that atomic hydrogen oscillator (or maser) is characterized by excellent frequency stability.However,it delivers a signal with power level of the order of 10-13W and a frequency of 1420.405 MHz,that is not practical for the users,and its output signal,in general,cannot be used directly.Therefore quartz-crystal oscilltor at a basic frequency has to be used and phase-locked to the hydrogen signal.This approach is shown in Fig.1.It is necessary to include a sensitive receiver and frequency synthesizer,thus,the frequency stability of the maser can be transferred to the quartz-crystal oscillator.

本文从分析锁定的石英振荡器的相对频率波动的功率谱密度出发,论述氢原子振荡器相位锁定的石英振荡器系统中,对各个部份的要求,其中包括锁相环的带宽,阻尼系数的选定。把平衡混频器作鉴相器用时必须满足的要求。以及接收机总通带的决定和各级放大量的分配。目的在于澄清过去研制中的盲目性和错误结论。
