摘要:
A combination of Muscovite Mica, Phosphate Glass, and CR-39 plastic track detectors has been successfully employed in studying the phenomena of forward-, and back-scattering of fission fragments from Perspex, AI, Cu, Ho, Au, Pb, Bi, and U targets of varying thicknesses. Two different geometries were used in these studies. It was found that the fraction of the scattered-out particles increases with the increasing“Z”of the target material and that only the top 600 Å or so thick layer of Bismuth is important for the scattering of Cf-252 fission fragments. Angular distribution measurements show that the scattered-out fraction decreases with the increasing angle of scattering. It has also been found that the evenness (on microscopic scale) of the target surface affects the fraction of the scattered-out fission fragments.
