Proton Polarizability Correction to the Hydrogen Hyperfine Splitting
The contribution of ∆ isobar to the correction on proton polarizability in the hyperfine splitting of hydrogen and muonic hydrogen is calculated with the account of the experimental data on N −∆ transition form factors. Talk presented at the Conference of RAS Nuclear Physics Department ”Fundamental Interactions of Elementary Particles” Moscow, ITEP, 16-20 November 1998
متن کاملProton Structure Corrections to Hydrogen Hyperfine Splitting
The largest uncertainty in calculations of hydrogen ground-state hyperfine splitting comes from corrections due to proton stucture. We review these corrections, with special mention of the inelastic, or polarizability, corrections which have been recently re-evaluated. Summing up the arguably best current values for the calculated corrections leaves us 1–2 ppm short of the experimental data. We...
متن کاملNuclear Structure-Dependent Radiative Corrections to the Hydrogen Hyperfine Splitting
Radiative corrections to the Zemach contribution of the hydrogen hyperfine splitting are calculated. Their contributions amount to −0.63(3) ppm to the HFS. The radiative recoil corrections are estimated to be 0.09(3) ppm and heavy particle vacuum polarization shifts the HFS by 0.10(2) ppm. The status of the nuclear-dependent contributions are considered. From the comparison of theory and experi...
متن کاملNew Evaluation of Proton Structure Corrections to Hydrogen Hyperfine Splitting
We consider the proton structure corrections to hydrogen ground-state hyperfine structure, focusing on a state-of-the-art evaluation of the inelastic nucleon corrections—the polarizability corrections—using analytic fits to the most recent data. We find a value for the fractional correction ∆pol of 1.3 ± 0.3 ppm. This is 1–2 ppm smaller than the value of ∆pol one would deduce using hyperfine sp...
متن کاملThe hyperfine structure of the hydrogen molecular ion
Theoretical investigations of the hyperfine structure of the hydrogen molecular ion (one electron and two protons) are discussed. The nuclear spin-rotation interaction has been found to be of the same sign as in the hydrogen molecule and the hyperfine transition frequencies can be accurately predicted. With measurements of the hyperfine structure of the deuterium molecular ion (or of HD) it sho...
