Using the recently derived primary cosmic ray nucleon spectrum from JACEE and GSFC balloon flight data and Fermilab results for pp → π ± + X anything inclusive reaction data in the light of Feynman scaling the depth‐intensity spectrum under standard rock has been estimated. A precisely constructed range‐energy relation has been applied in this analysis. The derived spectrum when corrected for range fluctuation agrees approximately with the experimental data under standard rocks measured by M IYAZAKI , B ARTON , C ASTAGNOLI et al., M EYER et al., B ERGAMASCO et al., S HELDON et al. and B ASCHIERA et al.
