摘要：

The energy loss distributions and dechanneling of MeV protons and antiprotons have been studied by computer simulation based on the binary collision model. It is found that a small fraction of antiprotons is channeled anomalously through a crystal. The average energy loss for antiprotons incident along a channel direction is larger (approximately 10%) than that for random incidence. It is also shown that the FWHM of the energy loss distribution for antiprotons strongly depends on the incident angle.
