Abstract

Measurements with the CASA-MIA experiment show the cosmic ray spectral knee to be a smooth transition. The composition is consistent with direct measurements at 100 TeV but becomes heavier through the knee region. The smooth change results from using a composition-independent energy reconstruction. Data are consistent with rigidity dependent cutoffs[1].
