Based on the diffusion model, the channeling fraction of antiprotons and electrons as a function of penetration depth is studied numerically. According to the calculations, the dechanneling length of antiprotons is of the same order of magnitude as that of electrons. It is found that, though the dechanneling length of antiprotons is much smaller than that of protons, a definite portion (≈ few %) of axially channeled antiprotons has anomalously large dechanneling length.
