# A new potential function form incorporating extended long-range behaviour: application to ground-state Ca2

@article{Roy2007ANP, title={A new potential function form incorporating extended long-range behaviour: application to ground-state Ca2}, author={R. L. Roy and Robert D E Henderson}, journal={Molecular Physics}, year={2007}, volume={105}, pages={663 - 677} }

A new analytic potential energy function form which incorporates the two leading inverse-power terms in the long-range potential is introduced and applied to a recently reported data set for the ground state of Ca2. The new function yields an accurate representation of data which span 99.97% of the well depth and involves only a fraction as many (between 1/3 and 2/3 fewer) parameters as were needed to define published potential functions for these systems based on the same data.
