- W41551188 abstract "An increase by a factor 20 in resolution is about as important when measuring the g-factor of the electron, as a 20-fold increase in accelerator energy is in high-energy physics. An antenna in a realistic spherical cavity resonator had been analyzed [1] by SCHELKUNOFF in ′43. PURCELL showed in ′46 that the 1 ife-time of atoms placed in a resonant cavity is greatly reduced. In a perfect non-resonant cavity one naively expects the opposite: no radiation can be lost, ergo no damping of an atomic oscillator. Indeed, a 10-fold increase in the lifetime was observed by GABRIELSE et al. in ′84. The reduction of the natural width by tuning between cavity resonances had been proposed by DICKE in ′59. After shooting an atomic beam through a parallel plate wave guide (λ/2 = 0.22 mm apart and reducing the decay rate >20-fol d, KLEPPNER et al., in ′85 nevertheless reached the conclusion, that cavity narrowing of spectral lines is ‘fundamentally flawed by nonradiative shifts’. Such pessimism is unjustified for an individual particle closely centered in a cavity» λ/2, VAN DYCK et al. ′81. Here, the trap electrodes form a microwave cavity good enough, to greatly reduce the natural line width, and, by proper relative tuning of cavity and atomic resonances, any shift of the atomic transition may be nulled." @default.
