    "abstract": "We extend the exactly solvable Hamiltonian describing $f$ quantum oscillators\nconsidered recently by J. Dorignac et al. by means of a new interaction which\nwe choose as quasi exactly solvable. The properties of the spectrum of this new\nHamiltonian are studied as function of the new coupling constant. This\nHamiltonian as well as the original one are also related to adequate Lie\nstructures.",
