CHARGE COMPOSITION OF HIGH ENERGY HEAVY PRIMARY COSMIC RAY NUCLEI

摘要

A detailed study of the charge composition of primary cosmic radiation for about 5000 charged nuclei from neon to iron with energies greater than 1.16 GeV/nucleon is presented. Integral flux values of 10≤z≤14 = 9.58× 10-1, 15≤z≤19 = 1.80 ×10-1, 20≤z≤23 = 1.51 ×10-1, and 24≤z≤28 = 2.37×10-1 particles/m2 sec-ster for rigidity greater than 4.9 GV and 10≤z≤14 = 1.54 ×10°, 15≤z≤19 = 2.90 ×10-1, 20 ≤z≤23 = 2.10 ×10-1 and 24≤z≤28 = 3.60 ×10-1 particles/m2-sec-ster for rigidity greater than 3.25 GV are reported and compared to other receat measurements at similar geomagnetic latitude. These values are obtained after corrections have been made for detector dependences, atmospheric attenuation and solar modulation.
