MEASUREMENT ON CROSS SECTION OF HIGH ENERGY IRON NUCLEUS (E≥4GeV/N)-ALUMINIUM NUCLEUS INTERACTIONS

  • For the purpose of nucleus-nucleus interaction detection, a detector consisted of CR-39 plastic track detector sheets interlayered with aluminium plates was launched to 37 km height by balloon near Beijing and exposured in the high energy nucleus beam of primary cosmic rays for 10 hours. The obtained Fe-Al interaction cross section (Δz≥1) at energy region higher than 4GeV/N is 1.76±0.18b.

MEASUREMENT ON CROSS SECTION OF HIGH ENERGY IRON NUCLEUS (E≥4GeV/N)-ALUMINIUM NUCLEUS INTERACTIONS

    Corresponding author: REN Guo-Xiao,

Abstract: For the purpose of nucleus-nucleus interaction detection, a detector consisted of CR-39 plastic track detector sheets interlayered with aluminium plates was launched to 37 km height by balloon near Beijing and exposured in the high energy nucleus beam of primary cosmic rays for 10 hours. The obtained Fe-Al interaction cross section (Δz≥1) at energy region higher than 4GeV/N is 1.76±0.18b.
