  We examine Maris' recent suggestion that the fission of electron-inhabited
bubbles in liquid helium may give rise to a new form of electron
fractionization. We introduce a one-dimensional toy-model--a simplified
analogue of the helium system--which may be analyzed using the Born-Oppenheimer
approximation. We find that none of the model's low-lying energy eigenstates
have the form suggested by Maris' computations, in which the bubbles were
treated completely classically. Instead, the eigenstates are
quantum-mechanically entangled superposition states, which the classical
treatment overlooks.
