Theoretical Study on Recoilless Fractions of Simple Cubic Monatomic Nanocrystalline Particles

Recoilless fractions of simple cubic monatomic nanocrystalline particles are calcula ted by using displacement displacement Green's function. The numerical results show that the recoilless fractions on the surface of monatomic nanocrystalline particles are smaller than those in the inner, and they decrease when the particle size increase, the recoilless fractions of whole monatomic nanocrystalline particles increase when the particle size increase. These effects are more evident when the temperature is higher.
