Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The paper analyzes the energy spectra (ES) of cosmic ray (CR) nuclei H, Ne, Si, Fe in the energy range from E = 1 MeV nucleon-1 to 1000 MeV nucleon-1. The calculated values of the ES are compared with experimental data obtained from the GOES and ACE spacecraft over 7 years of operation. A new effect has been discovered in near-Earth space: a bend in the energy spectrum of nuclei in the energy range from 8 to 50 MeV nucleon-1. A possible mechanism for the complex influence of space factors on CR fluxes in near-Earth space is discussed.
