M. Jentschel et al., ATOMIC COLLISION CASCADES STUDIED WITH THE CRYSTAL-GRID METHOD, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 115(1-4), 1996, pp. 446-451
Atomic collision cascades within crystals can be produced by recoils i
nduced by gamma-emission after thermal neutron capture, Subsequently e
mitted secondary gamma-quanta are Doppler shifted due to the motion of
the recoiling atom. We report on the first observation of structure l
ineshape observed by Gamma-Ray Induced Doppler broadening (GRID) exper
iments using oriented single crystals. These allow a detailed study of
the dynamics of atomic collision cascades and of interatomic potentia
ls in the bulk of materials.
