Abstract
A 3dimensional calculation of atmospheric neutrino flux is presented, andthe results are compared with those of a 1dimensional calculation. In this study, the interaction and propagation of particles is treated in a 3dimensional way including the curvature of charged particles due to the geomagnetic field, which is assumed to be a dipole field. The purpose of this paper is, limited to the comparison of calculation schemes. The updated flux value with a new interaction model and primary flux model will be reported in a separate paper. Except for nearly horizontal directions, the flux is very similar to the result of 1dimensional calculations. However, for nearhorizontal directions an enhancement of the neutrino flux is seen even at energies as high as 1 GeV. The production height of neutrinos is lower than the prediction of the 1dimensional calculation for nearhorizontal directions, and is a little higher for nearvertical directions. However, the difference is not evident except for nearhorizontal directions.
