A Large Family of Negative Charge Carriers in Liquid Helium

In 1969 Doake and Gribbon,1 using the Cunsolo technique2 for measuring charged particle velocities, found a negative charge carrier with a much higher mobility than either the normal positive or negative carrier studied for the past fifteen years. They found that this new species, rather than producing vortex rings, reached a velocity apparently limited by roton creation. They were able to produce it below 1.05°K with large electric fields and a radioactive a source. We have studied a new species having similar characteristics and have found that a large family of negative charge carriers can be produced in liquid helium.3
