ABSTRACT
The work will demonstrate that the >30 MeV solar energetic particle energy spectra are power-law functions of particle momentum, in conformity with the theoretical concept of particle acceleration by a shock in a turbulent medium. At <30 MeV, the particle propagation processes en route to the Earth orbit make the spectra gradually harder. Some characteristics of the set of energy spectra, which are important in terms of constructing the solar energetic particle models, are discussed.
INTRODUCTION
All the present-day energetic proton flux models are directly or indirectly relevant to the concept of the particle energy spectra. This follows from the fact that all of the models are constructed using the integral particle flux databases calculated from the measured differential fluxes on some assumptions concerning the form of the energy spectra. Any particular spectral form has an impact on the confidence level of all the models to be constructed. This is irrespective of how an integral particle flux dataset is used to construct a particular model for solar energetic particles, whether it is the database of different-energy particle fluence or peak flux distributions, whe
