摘要:
Protons in the region of 400 KeV have been used to study the channeling process in BaF2and CaF2. The rate of loss of protons from the 111 linear channel, stopping power, and critical angle for the channel were found. Two techniques were employed, namely observationof elastic scattering by the lattice ions, and alpha particles produced by the reaction19F(p,αy)16O, from the sharp resonance at 340 keV. Both techniques gave results in good agreement. The channel parameters were much closer together for the two crystals than had been anticipated on the basis of the large difference in charge between Ba and Ca.
