Short summary
We show, for the first time, an analytical relationship between the intermittency level and the magnetic spectral index in the slow-solar-wind turbulence. Our results supply an observational basis for numerical and theoretical studies of the intermittent turbulence. These results will also help to obtain more information on the contributions of the intermittent structures to the power spectra as well as on the physical nature of the energy cascade taking place in the solar wind.
