Abstract

Strong directional effects have been observed when 1.15 and 1.35 GeV/c protons, π+ and π, and deuterons penetrate through germanium crystals. Transmission, wide-angle scattering, and an attempt to do blocking distributions are obtained from experiments using position-sensitive drift chambers. Corresponding measurements of energy loss in germanium crystals are also presented. These experimental results are compared to theory for energy loss, and satisfactory agreement is obtained.

      Conversely, experimental knowledge about channeling of negative particles had been limited due to the lack of high-energy non-radiating beams of negatively charged particles and experimental difficulties to fabricate suitable crystals. Pioneering experiments at CERN have failed to detect channeling of high-energy negative particles, while under the same conditions it was clearly observed channeling of their positive counterparts [4–6]. Only recent experiments demonstrated the possibility to steer also negatively charged particle beams through bent crystals at the full bending angle [7–9].

      An example of such a difference of about 38% has been observed in a semiconductor detector exposed to pions of 5 GeV/c [11]. The kinetic energy of δ-rays escaping from the detector has been calculated by a method [9] adopted in the data analysis of germanium and silicon detectors exposed to a pion beam. This method takes into account: (1) the thickness of the detector and its geometrical boundary, (2) the angular and energy distribution of δ-rays, (3) the electron range [25] and (4) the spatial origin of δ-rays which is concentrated in the detector along the beam axis.
