摘要：

An analytical expression for paraxial trajectory starting in a magnetic field was obtained. Numerical simulations of non-paraxial trajectories in Glaser's bell-shaped magnetic field were made. The initial momentum of the electrons was taken into account. The position of the object - the electron source - was changed and the energy of the electrons was also changed. The problems of detection efficiency are discussed. (C) 2008 Elsevier B. V. All rights reserved.
