Triaxial separable potentials V(λ, μ,ν) = f
λ + f
μ + f
ν ≥ 0, with
admit three constants of the motion (see de Zeeuw 1985 for more details), for which we can take the following set:
λ, and v
ν are the velocity components in the (λ, μ,ν) coordinate system, and we recognize in E the binding energy per unit mass.
