Abstract

It is well known that a coherent system can bring a quantum interference between different energy eigenstates into an observable oscillation. Since an energy difference and a frequency are related with each other by the equation ΔE = ω we can make use of the oscillation to measure the energy difference of quantum states. In this experiment, the hyperfine splitting of positronium is measured using the quantum oscillation. The result is 203.324±0.044(stat.)±0.028(sys.) GHz. This value is consistent with the theoretical calculations.
