Abstract
It has recently been suggested that a bubble in liquid helium containing an electron could be excited into a state where the electron is divided between two smaller half bubbles, and that these “electrinos” would have increased mobility. This proposal is discussed critically, and it is concluded that, if such a state were to form, it would quickly collapse into an incoherent quantum superposition of two separated ground-state bubbles. All the measurable properties of this state are identical with those of a single bubble.
