Description
Exact analytical expressions for scattering lengths for potentials with four-parameter long-range tails of the form -Ar-2(r+ρ)-2-Br-ν(r+ρ)ν-4 are presented. Contributions due to a potential core, with the latter not specified explicitly, are taken into account through a short-range scattering length and a core radius. For ν≠2 and B≠0 the derived expressions contain the Bessel functions; for ν=2 or B=0 they contain elementary functions
