Abstract
The confined variational method is used to generate a basis of correlated Gaussians to describe the interaction region wave function for positron scattering from the H2 molecule. The scattering length was ?-2.7a0 while the zero energy Zeff of 15.7 is compatible with experimental values. The variation of the scattering length and Zeff with internuclear distance was surprisingly rapid due to virtual state formation at R?3.4a0. � 2009 The American Physical Society.
