Abstract
We describe a noise fluctuation technique to monitor the voltage perio dic electric susceptibility of ultra-small capacitance (congruent-to 1 0(-16) F) superconducting weak links operating at liquid helium temper atures. We show that this can yield information on the ground and low lying excited states of these weak links.
