Abstract We consider a relationship between the difference in spectral indices of the spectra of single hadrons and all hadrons ($ β_{sngl} $ − $ β_{h} $) and the difference in the indices of the spectra of galactic cosmic ray (GCR) protons and nuclei. It is demonstrated that at the mountain level the ratio ($ β_{p} $ − $ β_{Z} $)/($ β_{sngl} $ − $ β_{h} $) is always larger than unity, if ($ β_{sngl} $ − $ β_{h} $) > 0.1. From the experimental value $ β_{sngl} $ − $ β_{h} $ = 0.4 ± 0.05 we derive that, in the vicinity of E = 10 TeV, $ β_{p} $ − $ β_{Z} $ ≥ 0.49 ± 0.06 , i.e., $ β_{p} $ ≥ 3.09 ± 0.06.
