Further results in nuclear scattering radiography.
A further investigation of the nuclear scattering of 500-1000 MeV protons is described. Three-demensional information on the desity distribution within carbon, CH and H2O phantoms is obtained with a volume resolution of 2 mm3. The separation of scattering on hydrogen from that on heavier nuclei, such as carbon and oxygen, is demonstrated, providing the statistics are sufficient. Some preliminary measurements on animals are reported, but with a volume resolution limited by statistics to 43 mm3.
