Abstract
It is by now established that neutrinos mix, have (different) nonzero masses, and therefore oscillate. The oscillation parameters themselves, however, are not all well-known. An open problem is that of the neutrino mass hierarchy. We study the possibility of determining the neutrino mass hierarchy with atmospheric neutrinos using an iron calorimeter detector capable of charge identification such as the proposed monolith and ical/ino detectors. We find that such detectors are sensitive to the sign of the mass-squared difference, {delta}{sub 32}=m{sub 3}{sup 2}-m{sub 2}{sup 2}, provided the as-yet unknown mixing angle between the first and third generations, {thet...
