Abstract
We present a calculation of the natural oscillation spectrum of inhomogeneous non-neutral ultracold plasma. The collective modes of these plasma oscillations are recorded in experiments as absorption resonances of radio-frequency electric field. It is shown that in the presence of friction of the electronic component, a discrete spectrum of plasma eigenoscillations is formed. Dependence of the frequency of these resonances on the charge imbalance and on the expansion time is obtained. Good agreement with the experiments of different authors is noted.
