The Hyperfine Structure of Atomic Hydrogen and Deuterium

Abstract

of the same kind, the method of calculating matrix elements developed in reference 1 is applicable. The calculations are tedious, however, and the resulting expression for the energy in terms of cx, P, and c is rather complicated. Minimization of the energy leads to an optimum value for the binding energy of roughly 0.135 ev, when O. =P = (0.5)& an/ c = 0.052, approximately.

Observation of the hyperfine spectrum of antihydrogen

“…The work that led to these achievements also provided the first evidence for the anomalous magnetic moment of the electron [5][6][7][8] , inspired Schwinger's relativistic theory of quantum electrodynamics 9,10 and gave rise to the hydrogen maser 11 , which is a critical component of modern navigation, geo-positioning and very-long-baseline interferometry systems. Research at the Antiproton Decelerator at CERN by the ALPHA collaboration extends these enquiries into the antimatter sector.…”

The trapped-ion qubit tool box

“…Single atomic-qubit rotations were demonstrated long before the emergence of quantum information science (e.g. [13]). …”

Deviations from 2

“…Because the hyperfine theory for these two atoms was considered to be complete, the experimental values should have matched the theoretical ones. But Nafe et al observed a discrepancy of about 0.25% -well above the error associated with the calculated values, prompting the authors to comment, "Clearly this interesting deviation is worthy of further study" 1 .…”
