Spectroscopic constants of HHe molecular states dissociating into H(4s,4p,4d,4f)+He(1s2). Electronic dissociation energies De were calculated with reference to the respective dissociation limits. We note that Te is the adiabatic electronic transition energy from state A2Σ+, and T00 is the associated v′ = 0 to v″ = 0 transition energy. (a) theory, this work; (b) experiment (Ketterle 1990c).
