N2 - The stabilization fixed core stochastic variational method (FCSVM) was used to estimate the low-energy s-wave phase shifts for Ps scattering from Kr and Xe. As such, the results of calculations in the fixed core model for Xe were at variance with R-matrix calculation. The inclusion of the van der Waals interaction leads to substantial changes in the scattering length for both krypton and xenon.
