... spectrum

Note that throughout this paper the power spectra are expressed as vectorial forms in k-space. The one-dimensional forms can be obtained by multiplying by $4\pi k^{2}$ and $2\pi k$ respectively the three and two-dimensional power spectra. According to this notation the Kolmogorov spectral index is n=11/3.

... scale

Here we refer to the length $\Lambda$ as the magnetic field reversal scale. In this way, $\Lambda$ corresponds to a half-wavelength, i.e. $\Lambda= 0.5\cdot(2\pi/k)$ .
