  2. Two-body, experiment 4He - 4He First observation by Luo et al (1993) and Schollkopf, Toennies (1994) First measurement of the bond length by Grisenti (2000) Estimation of the binding energy and scattering length

  3. Two-body, theory 4He - 4He Potential models: Aziz et al. – HFD-B (1987), LM2M2 (1991) Tang et al. – TTY (1995) where and
