We report preliminary results on cavitation experiments in4He in the presence of a small number of free electrons in the liquid. At negative pressures insufficient to produce homogeneous nucleation we observed cavitation events which we ascribe to nucleation at electron bubbles. We present measurements of the threshold for cavitation at electrons over the temperature range 1.8 – 3.2 K.
