TL;DR
This study measures the energy-dependent ratio of Titanium to Iron in Galactic cosmic rays using the ATIC-2 experiment, providing insights into cosmic ray composition and propagation at energies from 5 to 500 GeV per nucleon.
Contribution
It presents the first measurement of the Ti/Fe flux ratio over a wide energy range using the ATIC-2 silicon matrix detector.
Findings
Ti/Fe ratio varies with energy in the measured range
Results improve understanding of cosmic ray propagation models
Data supports existing theories of secondary cosmic ray production
Abstract
Titanium is a rare, secondary nucleus among Galactic cosmic rays. Using the Silicon matrix in the ATIC experiment, Titanium has been separated. The energy dependence of the Ti to Fe flux ratio in the energy region from 5 GeV per nucleon to about 500 GeV per nucleon is presented.
