Higher-order corrections to the spin-orbit and spin-spin tensor interactions in HD
Mohammad Haidar, Vladimir I. Korobov, Laurent Hilico +1
Improved values of hyperfine coefficients related to the electronic spin-orbit and electron-nucleus spin-spin tensor interactions in the HD molecular ion are obtained through n…
Higher-order corrections to spin-orbit and spin-spin tensor interactions in hydrogen molecular ions: theory and application to H
Mohammad Haidar, Vladimir I. Korobov, Laurent Hilico +1
We consider higher-order corrections to hyperfine coefficients related to the spin-orbit and spin-spin tensor interactions in hydrogen molecular ions. The -order radia…
Proton-Electron Mass Ratio from Laser Spectroscopy of HD at the Part-Per-Trillion Level
Sayan Patra, M. Germann, J. -Ph. Karr +7
Accepted values of the masses of several subatomic particles have been under debate since recent measurements in Penning traps produced more precise yet incompatible results, imply…
Higher-order corrections to spin-spin scalar interactions in HD and H
Jean-Philippe Karr, Mohammad Haidar, Laurent Hilico +2
The largest hyperfine interaction coefficients in the hydrogen molecular ion HD, i.e. the electron-proton and electron-deuteron spin-spin scalar interactions, are calculated wi…
Trapping, cooling, and photodissociation analysis of state-selected H ions produced by (3+1) multiphoton ionization
Julian Schmidt, Thomas Louvradoux, Johannes Heinrich +4
We report on the production of cold, state-selected H molecular ions in a linear RF trap. The ions are produced by (3+1) resonance-enhanced multi-photon ionisation (REMPI) of…
Proton-electron mass ratio from HD revisited
Sayan Patra, J. -Ph. Karr, L. Hilico +3
We present a new derivation of the proton-electron mass ratio from the hydrogen molecular ion, HD. The derivation entails the adjustment of the mass ratio in highly precise the…
