Query: A proposed method for measurement of cosmic-ray chemical composition
  based on geomagnetic spectroscopy   The effect of the geomagnetic Lorentz force on the muon component of
extensive air shower (EAS) has been studied in a Monte Carlo generated
simulated data sample. This geomagnetic field affects the paths of muons in an
EAS, causing a local contrast or polar asymmetry in the abundance of positive
and negative muons about the shower axis. The asymmetry can be approximately
expressed as a function of transverse separation between the positive and
negative muons barycentric positions in the EAS through opposite quadrants
across the shower core in the shower front plane. In the present study, it is
found that the transverse muon barycenter separation and its maximum value
obtained from the polar variation of the parameter are higher for Iron
primaries than protons for highly inclined showers. Hence, in principle, these
parameters can be exploited to the measurement of primary cosmic-ray chemical
composition. Possibility of practical realization of the proposed method in a
real experiment is briefly discussed.
