Abstract
Particles produced at high energies are channeled into narrow forward cones. This channeling is tight enough so that particles produced in an aligned single crystal have a non-negligible chance of interacting with downstream nuclei. The interaction probability including lattice vibrations is estimated. "Super multiple scattering" in single crystals is considered and shown to make this technique less suitable for charged particles. Applications are suggested including the possibility of charmed-particle-interaction experiments.
