Abstract

We present a new measurement of atmospheric muons made during an ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio [Formula Presented] as a function of atmospheric depth in the momentum interval 0.3–0.9 GeV/c is presented. The differential [Formula Presented] intensities in the 0.3–50 GeV/c range and for atmospheric depths between [Formula Presented] are also presented. We compare these results with other measurements and model predictions. We find that our charge ratio is [Formula Presented] for all atmospheric depths and is consistent, within errors, with other measurements and the model predictions. We find that our measured [Formula Presented] intensities are also consistent with other measurements, and with the model predictions, except at shallow atmospheric depths.
