The resonance properties of nonequilibrium regions of phase-slip centers arising in tin films of different thicknesses under the influence of a dc transport current are investigated experimentally for films which are uniform over their width. It is confirmed that an important role in the mechanism of excitation of the non-Josephson oscillation (NJO) is played by the inelastic electron–phonon relaxation time τε of the charge imbalance. It is shown that two intercoupled resonance systems exist in samples containing phase-slip centers in the NJO regime. The change in shape of the amplitude–frequency characteristics of the NJO signal as the sample thickness is changed is explained by the influence of the transport electric current on the rate of relative tuning of the NJO frequency ω0 and the relaxation frequency ωr of the nonequilibrium region of the phase-slip center.
