Abstract
This paper gives a momentum-space representation of the Argonne V18 potential
as an expansion in products of spin-isospin operators with scalar coefficient
functions of the momentum transfer. Two representations of the scalar
coefficient functions for the strong part of the interaction are given. One is
as an expansion in an orthonormal basis of rational functions and the other as
an expansion in Chebyshev polynomials on different intervals. Both provide
practical and efficient representations for computing the momentum-space
potential that do not require integration or interpolation. Programs based on
both expansions are available as supplementary material. Analytic expressions
are given for the scalar coefficient functions of the Fourier transform of the
electromagnetic part of the Argonne V18. A simple method for computing the
partial-wave projections of these interactions from the operator expressions is
also given.
