Abstract: | Corrections to the third virial coefficient derived from the first-order three-body exchange forces, ΔC1(T), in helium, neon and argon have been calculated. Inclusion of ΔC1 and the corrections due to the non-exchange three-body forces leads to a satisfactory agreement with experimental data. |
