“…The Born-Oppenheimer potential for Hep can be calculated accurately using the Rayleigh-Ritz variational method. The results obtained for both thresholds indicate that crossing occurs in the vicinity of R = 1.25 a 0 [229]. A very accurate Born-Oppenheimer potential has been obtained by Strasburger and Chojnacki [230], using the Rayleigh-Ritz variational method and a basis set made up of 768 explicitly correlated Gaussian functions.…”

“…The forthcoming analysis can be greatly simplified by taking into account the characteristic spatial and energy scales of the interactions involved in H-H scattering. As pointed out in [5][6][7][20][21][22][23][24][25], the rearrangement transitions to protonium (Pn) and positronium (Ps) occur mainly at internuclear distances smaller than the rearrangement radius R r 1 au. For internuclear distances above R r the adiabatic approximation, leading to the separation of leptonic and hadronic motion, is well justified.…”
