Corrections to the third viri4 coefficient derived from the first-order three-body exchange forces, AC, (71, in helium, neon and argon have been calculated. Inclusion of aC1 and the corrections due to the non-eschaqe three-body forces leads to a satisfactory agreement vdith esperimental data.

Recently a new direct CI method was proposed by Siegbahn. In his approach a large list of formulas containing one-electron coupling coefficients is made, creating storage problems and high I/O rates. A method to calculate these coefficients is described and tests performed showing that on the CRAY-1
