Unaccompanied hadron flux at a depth of 730 g cm-2, 102<E<104GeV

Abstract
The energy spectrum of unaccompanied hadrons has been measured at a depth of 730 g cm-2 in the atmosphere. The energy was determined by a deep calorimeter (960 g cm-2) of area 4 m2. For charged hadrons unaccompanied in a 3.3 m2 spark chamber placed above the calorimeter, the observed flux was fitted in the energy range 100<E<10000 GeV.
