[en] Particle orbits in two-dimensional (2-D) kinetic equilibrium solutions for the magnetotail are considered. A comparison is made between the orbits in the equilibrium fields and those found in previous studies of the orbits where the main component of the magnetic field (B_x) was approximated as either a hyperbolic tangent or a linear function of z with the normal field (B_z) taken to be a constant (one-dimensional models). Here, the plane z = 0 defines the neutral plane. The orbits in the 2-D fields are found to be significantly different from those in the one-dimensional models. The particles are generally reflected in much shorter distances and the loss region is much smaller than in the one-dimensional fields. This holds true independent of ρ/L, where L is the current sheet thickness and ρ is the Larmor radius in the asymptotic field. For ρ/L approx-gt 0.1, the fraction of integrable orbits in the equilibrium fields also becomes different from that in the one-dimensional fields. As ρ/L becomes larger than 0.3 (with the exact value depending on the equilibrium model and particle position in the tail), the phase space becomes dominated by integrable orbits, whereas in the one-dimensional fields the phase space remains divided into integrable and chaotic regions. Another major difference between the orbits in the 1-D and 2-D fields lies in the fact that the equilibrium orbits have a net drift in the y direction whereas the orbits in the 1-D models have zero net drift. The relevance of the above finding to the problem of magnetic reconnection in the tail is discussed
