Channeling- und Blocking-Effekte bei Transmission von Deuteronen der Energie 16 bis 27,5 MeV durch Lithiumfluorid-Einkristalle

The energy loss of deuterons transmitted through single crystals of LiF has been studied as a function of incidence angle near the (010), (¯110) and (¯120) planes. In the spectrum of transmitted deuterons particles were found with higher and lower energy loss in addition to the deuterons with normal energy loss. The critical angle for channeling was calculated and compared with experimentell results. The yield of blocked deuterons as a function of incidence angle has been explained by a model, which describes the trajectories of blocked particles.
