摘要
The muonic hydrogen experiment measuring the 2P - 2S transition energy [ R. Pohl et al., Nature (London) 466, 213 (2010)] is significantly discrepant with theoretical predictions based on quantum electrodynamics. A possible approach to resolve this conundrum is to compare experimental values with theoretical predictions in another system, muonic deuterium mu D. The only correction which might be questioned in mu D is that due to the deuteron polarizability. We investigate this effect in detail and observe cancellation with the elastic contribution. The total value obtained for the deuteron structure correction in the 2P - 2S transition is 1.680(16) meV.
