M. Salerno et al., CANONICAL TRANSFORMATION BETWEEN INTEGRABLE HENON-HEILES SYSTEMS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(6), 1994, pp. 5897-5899
A canonical transformation between two known integrable cases of the H
enon-Heiles systems is given and the separation of variables for the c
orresponding Hamilton-Jacobi equations is discussed.
