The pair potential for helium has been computed with accuracy improved by anorder of magnitude relative to the best previous determination. For the wellregion, its uncertainties are now below 1 millikelvin. The main improvement isdue to the use of explicitly correlated wave functions at the nonrelativisticBorn-Oppenheimer (BO) level of theory. The diagonal BO and the relativisticcorrections were obtained from large full configuration interactioncalculations. The nonadiabatic perturbation theory was used to predict theproperties of the halo state of helium dimer. Its binding energy and theaverage value of interatomic distance are found to be 138.9(5) neV and 47.13(8){\AA}. The binding energy agrees with its first experimental determination of151.9(13.3) neV [Zeller et al., PNAS 113, 14651 (2016)].
