The RKR long-rtige potential of the B %I ecu state of I,, and the validity of the inverse-power expansion in respect of the internuclear distance have been investigated. Values of the long-range constants C's, C6 and C8 are obtained.
The 'Z: van der Waals potential curve of two interacting He\* (2 "S) atoms has been determined from multi-reference configuration interaction calculations with an estimated accuracy of about 1%. An analytical representation is given in terms of a damped dispersion expansion and exponential exchange
We construct Fredholm equations for the resolvent of a three-body Hamiltonian with longrange interactions at energies which are negative and different from those of the two-body thresholds. Furthermore we show that the homogeneous equations have a non-trivial solution at the energy E, iff E is an ei
