Precision cw Laser Spectroscopy of Hydrogen and Deuteriumpler-free spectra of this transition, obtainable by two-photon absorption, offer the prospect of precise tests of bound-state quantum electrodynamics (QED) and more accurate values for fundamental constants /1/. The two-photon absorption was first observed by HANSCH et al. /2/ at Stanford, in the fi

Antihydrogen Productionrage ring.[l] The mechanism is radiative recombination,.the extra energy being carried off by a photon. This process may be stimulated.with a possible increase of 100 in rate for stimulation to .=2 [2]. Nonetheless, the antihydrogen production rate in a subsequent proposal is still very low, less th

Atomic Physics in Confined Space: Suppressing Spontaneous Emission at Optical Frequencies and Measurs in which the mode distribution of the field is very different from its free space configuration, it is possible to strongly alter the atomic spontaneous radiation rates and transition frequencies. These Cavity Quantum Electrodynamics effects, as they are called, have been first demonstrated in the

The PNC neutral weak coupling is decribed by an effective zero-range pseudoscalar potential H. = H. + H. that must be added to the usual atomic Hamiltonian. The dominant portion H. involves the axial and vector parts of the electronic and nucleonic neutral weak currents, respecti
