Abstract
Using the steady–state leaky–box model for cosmic ray propagation in interstellar matter, along with the Alice Springs balloon flight data for sub Fe–Fe group, the escape length has been estimated and found to be 1.48 g/cm2 . The result is in fair agreement with the global fit to the escape length distribution surveyed by Ormes and Frier at the energy 100 GeV/n, which is comparable with our estimated source energy 86 GeV/n based on observed average energy and other propagational parameters.
