A recently developed theory of force-free electromagnetic oscillations (Osherovichm, 1985, 1986), is employed to interpret the diffuse plasma resonances stimulated by topside ionospheric sounders at the frequencies f{sub Dn}. The main prediction of the theory, namely, that the spectrum of frequencies should be proportional to n{sup 1/2}, n = 1, 2, 3, {hor ellipsis}, is checked against observations. It is found that f{sub Dn} {approx} 0.95(f{sub N}f{sub H}){sup 1/2}n{sup 1/2} is a fair approximation for diffuse ionospheric resonances, where f{sub N} and f{sub H} are the plasma and electron gyrofrequencies, respectively.
