Abstract
The voltage-current characteristics of a superconducting contact of submicrometer size between two monocrystalline filaments (of Sn, In, and Zn) show linear portions with discrete values of constant differential resistance. The observation may indicate the existence of excited states of a phase-slip center establishing in the contact. The phenomenon is not understood at present.
