Galactic electron spectra and propagation models

The differential spectrum of galactic electrons is determined. Calculations are carried out on the basis of a homogeneous model, a model of isotropic diffusion, a model of diffusive propagation of cosmic rays with regard to convection. Numerical solutions of the equations for these models under the assumption of the exponential spectrum of electron injection are presented. It is shown that the measured electron spectrum is in satisfactory agreement with the spectrum predicted by the homogeneous model and worse - with the rest models
